• – Smartest first step: a cloud readiness assessment and a pilot migration wave before you commit to a full program

Introduction

For most US businesses, cloud migration is no longer a question of if. It is a question of how fast, how safely, and with whom.

The market numbers make the urgency clear.

• The global cloud migration services market is expected to grow from $18.2 billion in 2026 to $146.6 billion by 2035, a 26.1% CAGR, with North America as the largest market (Global Market Insights).
• The US cloud professional services market is valued at about $20.9 billion in 2026 and projected to reach $37 billion by 2031, with cloud migration, security optimization and managed services named as the primary growth drivers (MarketsandMarkets).
• Gartner expects accelerating AI demand to push public cloud services growth to 21.3% in 2026, on the way to a $1.48 trillion market by 2029 (Gartner).

Behind those numbers is a simpler story. Legacy data centers are expensive to run, hard to secure, and almost impossible to scale for AI. At the same time, many companies that moved to the cloud early are now rethinking where they run. A growing number are consolidating from Azure onto AWS to simplify operations, reduce licensing costs, and tap into AWS’s broader service ecosystem.

But more money flowing into the cloud also means more ways for a migration to go wrong. Budgets get blown when workloads are lifted and shifted without optimization. Downtime creeps in when dependencies are not mapped. Compliance gaps appear when security is treated as a final step instead of a design principle.

That is why choosing among cloud migration companies matters as much as choosing the cloud itself. In this guide, we break down ten of the most credible providers serving US businesses in 2026: what each does best, where each falls short, who it fits, and the exact questions to ask before you sign.

How We Evaluated the Best Cloud Migration Service Providers

We did not rank providers on brand recognition or headcount alone. A 50,000-person consultancy is not automatically the right partner for a 200-person SaaS company, and an AWS-only boutique will not help a business that needs multi-cloud governance.

Instead, we assessed each provider on six criteria that consistently separate successful migrations from stalled ones:

We also weighed value for money. Many US businesses overpay for brand names, then discover that the actual migration work is subcontracted or handled by junior teams. Transparent pricing and senior engineering involvement counted in a provider’s favor.

Top Cloud Migration Companies at a Glance (2026 Comparison)

10 Best Cloud Migration Companies for 2026: Detailed Reviews

1. Wishtree Technologies

Best for: mid-market companies and enterprises moving from Azure or on-premises infrastructure to AWS, without enterprise-consultancy overhead

Headquarters: Lewes, Delaware, with offices in the UK and UAE

Core cloud focus: AWS (primary), with Azure and Google Cloud expertise for hybrid and multi-cloud estates

Wishtree Technologies is a US-registered digital engineering company that helps businesses move, modernize and optimize their workloads in the cloud. Where many providers stop at “getting you there,” Wishtree treats migration as the start of a modernization journey. The goal is a cloud environment that is cheaper to run, easier to secure, and ready for analytics and AI.

A large share of Wishtree’s migration work involves moving workloads from Microsoft Azure to AWS.

Companies make this switch for practical reasons: consolidating on one cloud after an acquisition, lowering licensing and compute costs, gaining access to AWS-native data and AI services, or aligning with partners and customers who already run on AWS.

Wishtree’s teams handle the hard parts of that move, from mapping Azure services to their AWS equivalents to re-engineering identity, networking and data pipelines.

Its intelligent cloud migration services combine AI-assisted discovery with phased migration waves. Dependencies are mapped before anything moves, workloads are grouped by risk and business value, and each wave is tested with rollback plans in place. The result is fewer surprises, less downtime, and earlier proof of value.

Key cloud migration services:

• – Cloud readiness assessment, TCO analysis and migration roadmap
• – Azure-to-AWS and on-premises-to-AWS migration
• – Rehosting, replatforming and refactoring based on the 7 Rs
• – Legacy infrastructure modernization for aging servers, databases and monolithic apps
• – Database and data platform migration, backed by Wishtree’s data engineering practice
• – DevSecOps and CI/CD pipelines built for the new environment
• – Cloud cost optimization and FinOps
• – AWS managed services and predictive cloud management and support after go-live

How a typical Wishtree migration runs:

1. Assess: inventory workloads, map dependencies, and estimate TCO on AWS versus the current environment.
2. Plan: choose an R strategy per workload, design the AWS landing zone, and set migration waves.
3. Migrate: move workloads wave by wave, with parallel runs and rollback plans.
4. Optimize: rightsize resources, tune costs, and harden security and compliance.
5. Operate: hand over to managed services, or train your in-house team to run the new environment.

Why it stands out:

• – AWS-first expertise with real Azure depth. Teams understand both sides of an Azure-to-AWS move, which reduces translation errors in identity, networking and data services.
• – Migration plus modernization. Wishtree does not just relocate technical debt. It modernizes as it migrates.
• – AI-ready outcomes. Data platforms are rebuilt so they are ready for analytics, machine learning and generative AI on AWS.
• – Security built in. Cybersecurity and AI-driven compliance are part of the design, not a final checklist.
• – Speed and flexibility. Engineers can start within 48 hours, with engagement models that range from full project delivery to staff augmentation.

Pros:

• – Strong value compared with large consultancies
• – Senior engineers involved from assessment to go-live
• – Combines cloud, data and AI engineering under one roof

Considerations:

• – Smaller brand footprint than the global consultancies, so a pilot wave is a good way to validate fit

AWS Specialists vs. Multi-Cloud Partners: Which Do You Need?

The providers above fall into two broad groups, and choosing the right group narrows your shortlist quickly.

The 7 Rs of Cloud Migration: Strategies Top Providers Use

Every credible cloud migration company uses some version of the 7 Rs to decide what happens to each workload. Knowing them helps you judge whether a provider’s plan makes sense, or whether they are defaulting to one approach for everything.

Most real migrations use a mix. A strong partner might rehost 40% of workloads for speed, replatform the databases, refactor two customer-facing apps, and retire a handful of tools nobody uses. A weak partner applies lift-and-shift to everything and leaves you with a bigger cloud bill than your old data center.

Azure to AWS Migration: What US Businesses Should Know

Migration is not only about leaving the data center. In 2026, a growing number of US companies are moving workloads from Microsoft Azure to AWS. The reasons are usually practical:

• – Consolidation: after a merger or acquisition, running two clouds doubles the tooling, skills and governance effort.
• – Cost and licensing: some organizations find better pricing models, savings plans and licensing flexibility on AWS.
• – Service breadth: AWS offers a wide catalog of data, analytics, machine learning and generative AI services.
• – Ecosystem alignment: partners, customers or marketplaces the business depends on often already run on AWS.

An Azure-to-AWS move is not a simple copy. Each Azure service needs a mapped AWS equivalent, and identity, networking and data layers usually need re-engineering.

When you evaluate cloud migration companies for an Azure-to-AWS project, look for teams that are fluent in both platforms. A partner that only knows AWS may miss Azure-specific dependencies, while an Azure-heavy partner may not design the AWS landing zone well.

How to Choose the Right Cloud Migration Company: A 7-Point Checklist

Shortlisting is easy. Choosing well is harder. Use this checklist to compare finalists on what actually predicts a successful migration.

1. Verify partner credentials. Look for current AWS, Azure or Google Cloud partner tiers and specific competencies, such as AWS Migration and Modernization. Logos on a website are not proof.
2. Ask for the migration framework in writing. A good partner can show you its assessment, wave planning, testing, cutover, and rollback approach before you sign anything.
3. Confirm US compliance experience. Ask specifically about HIPAA, SOC 2, PCI DSS, FedRAMP, or state privacy laws, depending on your industry, and request examples.
4. Demand cost transparency. Ask how they estimate total cost of ownership and how they prevent post-migration bill shock through rightsizing and FinOps.
5. Look beyond the move. Predictive cloud management and support after go-live often matters more than the migration itself.
6. Check modernization depth. Moving technical debt into the cloud only relocates the problem. Ask whether they can modernize as they migrate.
7. Test the fit with a pilot. Start with one workload or one migration wave before committing to a full program.

Questions to ask every cloud migration provider

• – Who exactly will work on our project, and how senior are they?
• – Which of our workloads would you rehost, replatform or refactor, and why?
• – How will you keep downtime to a minimum during cutover?
• – What happens if a migration wave fails?
• – How will our cloud costs compare with our current spend in the first 12 months?
• – What does support look like after go-live?
• – Can you share a similar migration you completed, ideally in our industry?

Red flags to watch for:

• – A fixed price quoted before any assessment
• – “Lift and shift everything” as the default strategy
• – Vague answers about security, compliance or data residency
• – No clear plan for rollback or testing
• – Senior experts in the sales meeting, but no commitment that they will stay on the project
• – No post-migration optimization or support offering

Common Cloud Migration Challenges (and How the Right Partner Solves Them)

Most failed migrations fail because of planning gaps, hidden dependencies, and weak governance. Here are the challenges we see most often:

Security deserves special attention. A migration is the best time to fix weak identity controls, unencrypted data, and inconsistent logging. Partners that build cybersecurity and AI-driven compliance into the migration design avoid painful rework later.

How Much Do Cloud Migration Services Cost in the USA?

There is no single price for cloud migration. Cost depends on how many workloads you have, how complex they are, which R strategy you choose, and how much post-migration support you need.

The biggest cost drivers are:

• – Number and complexity of workloads: a few virtual machines cost far less to move than hundreds of interconnected applications.
• – Migration strategy: rehosting is the cheapest upfront; refactoring costs more but usually delivers bigger long-term savings.
• – Data volume and sensitivity: large or regulated datasets need more planning, validation and security work.
• – Compliance requirements: HIPAA, PCI DSS or FedRAMP add design, documentation and audit effort.
• – Post-migration support: managed services and FinOps are ongoing costs, but they protect your savings.

As a rule, ask for a paid or free readiness assessment first. A credible TCO estimate from that assessment is worth more than any headline price.

How Long Does a Cloud Migration Take?

Timelines vary just as widely. As a general guide:

• – Small migrations (a handful of applications, mostly rehosting): a few weeks
• – Mid-sized programs (dozens of applications with some replatforming): a few months
• – Large enterprise programs (hundreds of applications, refactoring, multiple regions): many months to over a year, delivered in waves

The smartest approach is to migrate in waves. Early waves deliver value quickly and build confidence, while later waves benefit from lessons learned.

Cloud Migration Trends Shaping 2026

• – AI-assisted migration: AI tools now speed up discovery, dependency mapping, code analysis, and even refactoring.
• – AI-ready infrastructure: many companies now migrate so they can run AI workloads. As Gartner notes, AI demand is a major driver of cloud growth this year.
• – Cloud consolidation: more organizations are moving from multi-cloud sprawl to one primary cloud, often AWS, to simplify operations.
• – FinOps by default: cost governance is now built into the migration plan rather than added after the first surprise bill.
• – Hybrid and sovereign cloud: regulated US industries want tighter data residency, governance, and control.
• – Security-first design: zero trust, identity-centric security and automated compliance are becoming standard requirements.

Moving workloads is only step one. If your end goal is AI, your data layer needs attention too; see our take on AI implementation challenges.

Frequently Asked Questions (FAQs)

What do cloud migration companies do?

Cloud migration companies help businesses move applications, data, and infrastructure from on-premises systems or another cloud to platforms like AWS, Azure, or Google Cloud. Their services usually include readiness assessment, migration planning, execution, security, testing, and post-migration optimization and support.

How do I choose the best cloud migration company for my business?

Start with your target cloud and workload complexity. Then compare providers on partner credentials, migration methodology, compliance experience, cost transparency, modernization capability, and post-migration support. Running a pilot migration wave is the most reliable way to test the fit.

How much do cloud migration services cost in the USA?

Costs depend on the number and complexity of workloads, the migration strategy, data volume, compliance needs, and ongoing support. A detailed readiness assessment with a total cost of ownership estimate is the best way to get a realistic figure.

How long does a cloud migration take?

Small migrations can take a few weeks, mid-sized programs a few months, and large enterprise programs many months or more. Migrating in waves delivers value earlier and reduces risk.

Why are companies migrating from Azure to AWS?

Common reasons include consolidating onto one cloud after mergers, improving cost and licensing flexibility, accessing AWS’s broad data and AI services, and aligning with partners or customers that already run on AWS.

What are the 7 Rs of cloud migration?

The 7 Rs are rehost, replatform, refactor, repurchase, retire, retain, and relocate. Each is a different approach to moving a workload, and most migrations use a mix of them.

Is cloud migration secure?

Yes, when it is planned well. A strong partner builds encryption, identity and access management, compliance controls, and monitoring into the migration from the start, rather than adding them afterward.

Should I choose an AWS-only partner or a multi-cloud partner?

If you are committed to AWS, an AWS-focused partner offers deeper expertise. If you are moving from Azure to AWS, choose a partner fluent in both. If you will run several clouds long term, a multi-cloud partner with strong governance is a better fit.
