Choosing a cloud migration company might be one of the most important IT decisions your organisation makes this decade. It’s right up there with choosing your cloud platform, selecting your cybersecurity stack or deciding whether to trust your teenage kid to borrow the car (“Of course I’ll be careful, Mum.” Yeah… right).
Here’s the truth people rarely say out loud – Moving to the cloud is easy. Moving to the cloud properly is not.
A good cloud migration company will protect your data as if it were their own, guide you step by step, remove risk, simplify everything, and leave you feeling confident.
A bad one can leave you with Broken apps, unpredictable costs, security gaps, downtime, unhappy users and a migration that drags on for months longer than it should.
So how do you choose the right partner? Which cloud migration service providers are worth trusting? And what questions should you ask to separate the experts from the improvisers?
In this blog, we look at 12 questions you must ask any cloud migration company before you sign anything. These questions will help you spot red flags, highlight strengths and ensure you choose a partner who knows what they’re doing.
1. “How many cloud migrations have you successfully completed?”
This sounds basic, but you’d be shocked at how many cloud migration service providers are very new to the game. Real experience matters. You want a company that can say things like:
- “We’ve migrated dozens of large environments.”
- “We’ve handled complex legacy systems.”
- “We’ve done this before in your sector.”
Real migrations come with surprises and only seasoned teams know how to handle them calmly and efficiently.
2. “Can you explain your migration approach in plain English?”
If they drown you in jargon, buzzwords or long diagrams before you’ve even asked a question… run. A good cloud migration company should be able to explain its approach simply:
- Assess
- Plan
- Migrate
- Test
- Cutover
- Support
If they can’t explain it clearly, they won’t execute it clearly.
3. “Which cloud platforms do you specialise in?”
Every provider has strengths. Some are amazing with:
- Azure
- AWS
- Google Cloud
- Oracle Cloud Infrastructure (OCI)
- Hybrid cloud
- Multi-cloud
- Private cloud
But here’s the key question…
Are they recommending the right platform for you, or the one that gives them the best margin?
A trustworthy partner chooses platforms based on workload fit, performance, compliance, cost, scalability, total cost of ownership and your future strategy. Not incentives.
4. “What is your experience with legacy systems?”
To put it politely… Not everything in the real world is modern, cloud-ready or well-documented.
Some systems are:
- Old
- Custom-built
- Vendor-locked
- Fragile
- On outdated operating systems
- Dependent on old hardware
A good cloud migration partner doesn’t panic when they see these. A great one says:
“Yes – we’ve seen this before. Here’s what we’ll do.” Legacy experience is a huge differentiator.
5. “How do you minimise downtime?”
Downtime is one of the biggest fears organisations have about cloud migration. You want a provider who can talk confidently about:
- Phased migrations
- Sync migration
- Replication
- Lift-and-shift
- Live cutover
- Blue/green deployments
- Rollback options
- Testing
If they can’t explain how they avoid downtime, they’re not ready to lead your migration.
6. “How do you keep our data secure during the migration?”
Migration is one of the riskiest times for data. Your cloud migration company should have clear answers about:
- Encryption in transit
- Encryption at rest
- Identity and access controls
- Secure transport channels
- Tokenised access
- Firewall rules
- Zero-trust principles
- Logging and audit trails
If they say “the cloud provider handles that”, that’s a red flag. Migration security is their responsibility too.
7. “Do you provide cost modelling and TCO forecasts before we move?”
A responsible migration partner helps you understand:
- Cloud operating costs
- Storage costs
- Compute costs
- Networking fees
- Licensing impacts
- Data transfer charges
- Reserved instance options
- Scalability implications
If they can’t walk you through a realistic cost model, you may end up with a nasty surprise later.
And nobody wants CFO rage.
8. “Do you modernise as part of the migration, or simply move what we have?”
Some companies only do lift-and-shift. Others help you:
- Optimise applications
- Modernise workloads
- Replace legacy tools
- Right-size cloud resources
- Improve performance
- Reduce cost
- Update security
The right approach depends on your business. A good cloud migration company explains the options. A great one helps you choose the right balance.
9. “What happens after the migration—do you offer ongoing support?”
This is a big one that many people overlook. A migration isn’t finished when your workloads land in the cloud. You still need:
- Monitoring
- Cost optimisation
- Performance tuning
- Security updates
- Patch management
- Backup and DR
- Access control management
- Ongoing cloud advice
If your migration company disappears after cutover, you’re left holding the responsibility alone. The best cloud migration service providers stay by your side.
10. “Can you show us examples, case studies or references?”
If they have experience, they’ll have proof. A confident cloud migration partner will happily connect you with real customers. If they hesitate, avoid, or offer excuses, you’ve found your answer.
11. “What size projects do you specialise in?”
Some companies are perfect for large enterprises; others are mid-market or small businesses focused. You might find your partner overstretched if the project is too big or underutilised if it’s too small. You want a partner whose experience matches your scale.
12. “How do you ensure the migration won’t disrupt our users?”
This question separates the careful planners from the accidental chaos-makers. Look for answers involving:
- User communication plans
- Migration windows
- Training
- Phased rollouts
- Testing environments
- Shadow IT detection
- Pilot migrations
- Change management
If they say, “users won’t notice anything,” challenge them. Users always notice something. A good provider minimises the impact. A great one sets expectations, communicates clearly and makes users feel supported.
Bonus Question: “Are you listening to what we actually need?”
This is the most important question, even though you don’t ask it out loud. You look for it in how they:
- Respond
- Explain
- Recommend
- Ask questions
- Build trust
- Treat your business
- Tailor their approach
If they prescribe a solution before understanding your environment, you’re not dealing with experts. Experts listen first. Then design. Then execute.
Final Thoughts: Choose the Cloud Partner That Feels Right
You don’t need the biggest cloud migration provider. You don’t need the flashiest. You don’t need the one with the loudest marketing budget. You need the one that:
- Understands your organisation
- Respects your people
- Protects your data
- Design a plan that fits your reality
- Tells you the truth
- Knows the pitfalls
- Supports you fully
- And makes the entire experience feel safe, calm and controlled.
Ask the questions in this guide. Compare the answers. Listen for confidence, not clichés. Look for trust, not tension. Choose the cloud migration partner that feels like a team you genuinely want to work with – not the one pushing you into a decision. Your cloud migration is too important to get wrong. Choose the partner that will get you to the summit – safely, confidently and with far less stress than you expected.
