3 Strategic Steps Before Migrating to AWS

Migrating to AWS often gets framed as a technical project. But organizations that treat a cloud migration as purely a technical exercise tend to learn an expensive lesson: the technology isn’t usually the hard part.

The challenge is everything around it. Work changes, who owns what changes, and the decisions you used to make casually now need structure. To successfully migrate to AWS, there are a few strategic moves to make before jumping into the migration plan.

1. Treat It as an Organizational Change, Not a Technical One

Moving to AWS isn't just relocating infrastructure. It's changing the way the organization operates. The applications may look the same to end users, but how teams support, monitor, secure, and pay for them is fundamentally different.

Process changes and operational changes are inevitable. The teams who used to manage physical servers now manage cloud services. Procedures and runbooks look different. The day-to-day rhythm of supporting an application changes. Address these changes up front so teams aren’t left to figure it out on the fly.

Two things deserve real investment here:

• Change management. Put genuine emphasis on what it means to move to the cloud versus running traditional on-prem infrastructure. People need to understand not just the "what" but the "why," and they need to be brought along rather than surprised.
• Training. Cloud skills don't appear overnight. Budget for them deliberately. Investing in your team's cloud capabilities early pays off far more than scrambling to upskill after go-live, or worse, becoming dependent on outside help for everything.

The bottom line: you're changing how you do things, not just where you do them. Plan accordingly.

2. Build Cross-Functional Ownership

Cloud migration is more than infrastructure. It touches far more of the organization than the people who manage servers.

A move to AWS affects:

• Infrastructure teams, who adopt entirely new tools and operating models
• Application owners, whose applications now run and behave differently
• Security and networking, who must rethink how they protect and connect everything
• Finance, who shift from predictable capital expenses to consumption-based, variable cloud spend

If only the infrastructure team owns the migration, every other group becomes a bystander until something affects them, at which point there’s greater pushback. The fix is to establish ownership across all of these groups before the migration begins. When each function has a defined role and a stake in the outcome, there’s greater buy-in. Everyone understands their piece, and no one feels like the cloud is being done to them.

Define these ownership lines early. It's far easier than untangling confusion mid-migration.

3. Define Governance Up Front

This is where organizations most often shortcut and most often regret it. Before migrating a large group of applications, decide how decisions will get made.

Don't move first and figure out the rules later. Establish the foundation before starting:

• Standards. What does a properly configured, secure, well-architected environment look like for the organization?
• Operating model. How will the cloud be run and supported day to day, and by whom?
• Decision rights. Who has the authority to make which calls? Who approves new services, spending thresholds, and exceptions?

Many organizations formalize this by setting up a Cloud Center of Excellence (CCoE), a dedicated group responsible for setting standards, guiding teams, and maintaining consistency as adoption scales.

The goal is simple: don't make these decisions on a whim, one migration at a time. Deciding standards reactively leads to sprawl, inconsistency, runaway costs, and security gaps that are painful to fix later. When governance is defined up front, every subsequent move happens on a solid foundation.

The Common Thread

Notice what all three of these have in common: they’re all strategic. They're about people, ownership, and decisions. Get the organizational change, the cross-functional ownership, and the governance right before migrating, and the technical work becomes the easy part.
