Cloud Migration: DIY or Hire Experts?
Moving to the cloud is one of the most important IT decisions of the coming years. But is it worth handling the project internally — or does an external partner save time, money, and nerves in the end? An honest look at both paths.
What a Cloud Migration Really Involves
A cloud migration sounds like "moving servers." In reality, it involves much more: rethinking application architecture, rebuilding networks, adapting security concepts, meeting compliance requirements, and training your team on new technologies.
A simple lift-and-shift — moving existing servers 1:1 — is the simplest path. But it often wastes the cloud’s advantages: scalability, cost efficiency, and automation. If you want to use the cloud properly, you need to go deeper.
DIY vs. External Partner — the Comparison
| Criterion | DIY | External Partner |
|---|---|---|
| Timeline | 6–18 months — depending on learning curve and team size | 3–6 months — experienced team with proven track record |
| Risk | High — learning by doing with critical infrastructure | Calculated — known pitfalls are avoided |
| Knowledge Building | Slow and expensive — training, certifications, trial & error | Immediately available — expertise from day 1 |
| Ongoing Costs | Team + wrong decisions + opportunity cost | Project-based and predictable |
| Operations After Migration | Own team must be permanently available | Handover to internal team or managed service |
| Control | Full control, but also full responsibility | Shared responsibility with clear SLAs |
The Hidden Costs of DIY
An external partner’s hourly rate is higher — but the total bill often looks different than expected.
What DIY Really Costs
- Learning curve: 3–6 months of productivity loss until the team is cloud-ready
- Architecture decisions that only surface months later
- Opportunity cost — your team works on the migration instead of the product
- Downtime risk without migration experience — every hour of outage costs
What an External Partner Costs
- Higher hourly rate, but significantly shorter project duration
- Fewer mistakes through proven migration patterns and best practices
- Knowledge transfer included — your team learns during the project
- Predictable costs instead of unpredictable budget overruns
When Each Path Fits
Handle Migration Yourself
Fits when you have the resources and time — and want to build cloud know-how internally.
- IT is your core business
- Own cloud team already in place
- Simple lift-and-shift without re-architecture
- No time pressure — flexible timeline possible
Hire Experts
Makes sense when the migration is complex, time is pressing, or cloud experience is lacking in the team.
- First cloud migration in the company
- Complex application landscape with many dependencies
- Time pressure from contract expiry or compliance deadlines
- No internal cloud know-how available
Hybrid Approach
The golden middle ground: external expertise for the critical phases, internal team learns along and takes over.
- Own team should build long-term cloud competence
- Partner for architecture and critical migration phases
- Knowledge transfer is an explicit project goal
Our Honest Conclusion
A DIY cloud migration is feasible — if you have an experienced cloud team, no tight deadline, and a manageable application landscape. In this case, the internal path can make sense because you keep the know-how in-house long-term.
For the first cloud migration or complex landscapes, an external partner almost always pays off. Not because of the hourly rate — but because the mistakes you avoid would be more expensive than any consulting.
At devRocks, we follow a clear approach: we make ourselves dispensable. Our goal is to transfer knowledge rather than create dependencies. After the migration, your team should be able to operate the infrastructure on their own — or you consciously choose managed services.
Frequently Asked Questions
How long does a cloud migration take?
It depends heavily on the complexity. A simple lift-and-shift migration of individual workloads can be completed in a few weeks. A full cloud-native transformation with re-architecture typically takes 6–18 months. Decisive factors include the number of systems, dependencies between applications, and the availability of DevOps expertise on the team.
What does a cloud migration cost?
Migration costs vary significantly depending on scope and approach. As a rough guide: A simple migration with few workloads starts at €10,000–30,000. More complex projects with re-architecture and multiple teams range from €50,000–200,000+. Add ongoing cloud operating costs, which are often lower than on-premise in the long run.
Lift-and-shift or cloud-native — which is better?
Neither is inherently better — it depends on your goals. Lift-and-shift is faster and cheaper to migrate but brings fewer cloud benefits. Cloud-native requires more rework but enables auto-scaling, better availability, and lower operating costs. Many companies start with lift-and-shift and then modernize incrementally.
What risks are there in a cloud migration?
The most common risks are data loss during migration, unplanned downtime, cost explosions from incorrectly sized cloud resources, and security gaps from misconfigurations. Most risks can be significantly reduced through thorough planning, a pilot phase, and experienced guidance.
When should we involve an external partner for the migration?
External support is especially worthwhile when your team has little cloud experience, business-critical systems are being migrated, or the migration is under time pressure. An experienced partner avoids common mistakes, accelerates the process, and ensures clean architecture — instead of expensive corrections during live operations.
