A CTO’s Checklist for Choosing the Right Cloud Migration Company

Choosing a cloud migration company is one of the highest-stakes vendor decisions a CTO makes all year. Get it wrong, and you inherit a stalled project, a blown budget, and a system nobody fully understands.

And there’s always a chance you’ll get this wrong cause you may run this evaluation only once every few years. That inexperience is exactly what a polished sales team is trained to exploit.

Thankfully, below is a concrete checklist to help you in this regard, leveling the playing field before a contract gets signed. Every criterion here is grounded in real deployments, not vendor marketing copy.

But First, Here’s Why the Wrong Cloud Migration Companies Cost More

Migration failures rarely announce themselves upfront. They show up months in, as scope creep, missed deadlines, and mounting change orders. By then, switching partners costs more than starting over.

Cloud migration companies vary wildly in what they actually deliver. Some specialize in lift-and-shift with no modernization plan. Others oversell automation capabilities they don’t really have in-house.

The cost of picking wrong is measurable, not theoretical. McKinsey research on cloud migration missteps found inefficient migrations cost the average company 14% more than planned every year. Across three years, that waste adds up to more than $100 billion globally.

Timelines slip just as often as budgets do. The same research found 38% of companies see migrations delayed by more than a full quarter. Only 15% finish on schedule after moving most of their workloads.

Talent gaps compound the problem further. Most companies only staff about 35% of their cloud needs internally. Many will need to hire or reskill at least a million cloud developers industry-wide over the next three years.

That gap is exactly where the right partner earns their fee. It’s also exactly where a weak cloud migration company tends to hide thin bench strength behind a confident sales pitch.

What Cloud Migration Consulting Should Actually Include

Cloud migration consulting worth paying for starts with an honest assessment, not a sales pitch. A real consulting engagement maps your actual dependencies before proposing a single tool or timeline.

Discovery should surface which applications are safe to lift-and-shift and which need re-architecting first. Skipping this step is how “simple” migrations turn into year-long ordeals nobody budgeted for.

A capable partner also brings a documented rollback plan for every phase. If cutover night goes wrong, there needs to be a tested way back that doesn’t involve improvising under pressure.

The right cloud migration services build every engagement around that kind of upfront rigor. Skipping discovery to save two weeks upfront routinely costs months on the back end.

Communication cadence is another thing to pin down before signing. Weekly status calls that just restate a Gantt chart aren’t the same as a partner surfacing real risks early. Ask how they escalate a problem the moment it appears, not after it’s already blown the timeline.

Case Study: Cloud ERP Migration with Sub-15-Minute Recovery

National Janitorial Solutions needed to modernize a cloud ERP processing more than 500,000 work orders annually. The system had to preserve SOC2 Type II compliance throughout the entire migration.

DPL rebuilt the environment on Amazon ECS with Aurora MySQL, backed by fully automated CI/CD pipelines through AWS CodePipeline. Multi-region disaster recovery was designed in from day one, not bolted on afterward.

The results speak to what disciplined migration planning delivers. Recovery time objective landed under 15 minutes. Deployment frequency moved from weekly to daily, with manual deployment effort cut by 90%.

None of those numbers happen without a partner who plans for failure, not just success. Also, none of it happened overnight. The team phased the migration by service, validating each one under production load before moving to the next. That discipline is what a checklist item like “rollback plan” actually looks like in practice.

Who Supports the System After Migration Day

A cloud migration company that disappears after cutover leaves you managing an unfamiliar environment alone. Ask upfront whether ongoing support is part of the engagement or a separate line item entirely.

Post-migration issues rarely show up in the first week. They surface weeks later, once real production traffic and edge cases start hitting the new environment under normal business conditions.

Cost anomalies follow a similar pattern. Nobody notices an oversized instance or an idle load balancer during the migration itself. Those add up fast once the environment runs unattended for a full billing cycle.

DevOps managed services exists specifically for that stretch after go-live. A migration partner who also owns operational support has real incentive to build something stable. That’s different from a partner optimizing only for passing a final demo.

Ask how incident response works in the first 90 days post-migration. A vague answer here often means the relationship ends the moment the invoice is paid.

Evaluating Cloud Migration Solutions Before You Sign

Cloud migration solutions differ sharply depending on what you’re actually moving. A stateless web app migrates very differently than a regulated, stateful database with strict uptime requirements.

Ask any prospective cloud migration company to walk through their approach for your specific workload types. A generic methodology deck isn’t the same as a plan built for your systems.

Vague answers here are an early warning sign worth taking seriously. A partner who can’t get specific about your workloads probably hasn’t migrated many systems like yours before.

Container-based workloads need a different playbook than monolithic legacy applications. Database migrations bring their own replication and cutover challenges entirely separate from application-tier concerns. A good partner treats each category differently instead of applying one template everywhere.

Pricing structure matters too, and not just the headline number. Ask how change orders get handled once discovery reveals more complexity than the original scope assumed. That’s where budgets quietly blow up.

Also, take into consideration your workload, not the migration method. Cloud migration solutions should account for application dependencies, performance requirements, security, cost, and business criticality before deciding whether to rehost, replatform, refactor, replace, or retire a workload.

Matching the strategy to the workload reduces unnecessary complexity and helps ensure migration delivers a measurable business outcome.

Cloud Consulting Company Red Flags to Watch For

A cloud consulting company that can’t name specific tools, versions, and architectures is selling process, not expertise. Vague references to “best practices” without specifics should raise real concern.

Watch for a partner who can’t produce reference customers in your specific industry or compliance environment. Government, healthcare, and finance all carry constraints a generalist consultancy may not have handled before.

Team continuity is another quiet red flag worth probing. Ask who actually does the hands-on work versus who shows up only for the pitch. A senior team in sales calls that vanishes after signature is a common and costly bait-and-switch.

Recent industry survey data underscores how much is riding on vendor selection right now. PwC’s 2025 EMEA Cloud Business Survey surveyed more than 1,400 technology leaders across 26 territories. It found 86% now call AI capability decisive when picking a cloud provider.

Yet the same survey found only 29% are actually scaling those capabilities in production. That gap between vendor promises and delivered reality is exactly what a rigorous evaluation process should catch early.

Also watch how a vendor talks about failure. Anyone claiming a perfect track record across every past migration isn’t being fully transparent. Real partners can describe what went wrong and how they fixed it.

Why Application Modernization Consulting Belongs in the Conversation

Application modernization consulting should sit inside the same conversation as migration, not follow it as an afterthought. Moving a poorly architected application to the cloud unchanged just moves the same problems somewhere more expensive.

A genuine modernization assessment looks at several things. Which applications benefit from containerization? Which need database re-platforming? Which should be retired outright instead of migrated at all?

Not every legacy system deserves a share of the migration budget. Some applications cost more to modernize than to simply replace with a modern SaaS alternative. A capable partner tells you that even when it shrinks their own contract.

Sequencing also matters more than most RFPs account for. Modernizing before migrating sometimes makes sense. Other times, migrating first and modernizing in place works better. A strong partner explains that tradeoff honestly instead of defaulting to whichever approach fits their standard package.

💡 Need to separate genuine expertise from a polished sales pitch? Look for evidence of hands-on experience, not just certifications or a long list of cloud services. Cloud consulting companies should be able to explain their architecture decisions, migration approach, risk management, and measurable outcomes—and show how that expertise translates into value for your specific environment.

Building Your Final Shortlist

Narrowing a cloud migration company shortlist comes down to a few concrete tests. Ask for a detailed discovery-phase plan specific to your environment, not a generic template.

Request named references from similar-scale migrations, ideally in your industry. Confirm their team has hands-on certifications, not just partnership badges from cloud providers.

Push on rollback planning, change-order policy, and how they staff the engagement day to day. Those three answers reveal more about delivery quality than any pitch deck will.

Weigh price against specificity, not against the lowest number on the table. The cheapest proposal is rarely the cheapest migration once change orders and delays get factored in.

DPL has run this exact evaluation process from both sides. We’ve been the vendor under scrutiny, and we’ve helped clients scrutinize others before signing. Our cloud & DevOps services practice can walk through what your specific migration actually needs before you commit.
