Migration and Modernization

Our data center and VMware costs keep going up.

For CIO, CFO, VP of infrastructure

First, you receiveAssessMigration business case · Application disposition (7Rs) and wave plan · Fixed-price mobilize proposal
Timing and scopeAssess: fixed fee. Build: fixed scope, scoped per wave. Run: optional, monthly.
What happens nextA written recommendation. If you proceed, a scoped proposal for the next stage.

Hardware refreshes, lease ends and VMware licensing changes force a decision about where workloads should run. We start with a fixed-fee Migration Assessment: we discover what you have, decide what happens to each application using AWS's 7Rs, and build a business case. Not every workload should move; some stay or retire. Then we migrate in planned waves with tested rollback, covering VMware and Microsoft estates, and modernize applications and databases where it pays off.

How we work

What we do

Open a step to see what happens and what you receive.

Assess

Fixed fee.

  • Discover servers, applications and dependencies
  • Assign a 7Rs disposition to each application: retire, retain, rehost, relocate, replatform, repurchase or refactor
  • Build a total cost of ownership model and business case
  • Check eligibility for AWS migration programs

You receive: a migration business case, an application disposition and wave plan, and a fixed-price mobilize proposal.

Confirmed at scoping.

Build

Fixed scope with milestones, following the AWS Migration Acceleration Program sequence: assess, mobilize, then migrate and modernize.

  • Mobilize: migration runbooks, a pilot wave, cutover and rollback plans, and team enablement
  • Wave-based rehost and replatform moves with AWS Application Migration Service
  • VMware exit to Amazon EC2 or managed services, in stages
  • Windows Server, SQL Server and Active Directory migration with license optimization
  • Application and database modernization: containers (Amazon ECS or EKS), serverless, Amazon Aurora or RDS

You receive: migrated workloads per wave, cutover and rollback records, and a decommission plan.

Scoped per wave.

Run

Optional. If you want us to, we can keep this going monthly for as long as you need it.

  • Hypercare after each wave
  • Handover into Managed AWS Operations, if you choose it
  • Post-migration optimization review

You receive: a post-migration cost and performance report.

Services included: Migration Assessment and Business Case, Migration Readiness and Planning, Workload Migration, VMware Exit to AWS, Microsoft Workloads on AWS, Application and Database Modernization.

Each outcome is labelled with the stage that delivers it. An assessment or advisory engagement on its own does not include the implementation work.

Good to know

Questions leaders ask

What are the 7Rs?

Retire, retain, rehost, relocate, replatform, repurchase and refactor: the seven choices for each application.

How long does a migration take?

It depends on the number of applications and dependencies. The assessment produces a wave plan, and we confirm the schedule in the proposal.

Do we have to move everything?

No. Some workloads should stay where they are or be retired. The business case shows which.

Can AWS fund this?

AWS runs funding programs for some migrations. We check eligibility during scoping and never assume funding in a quote.

We tried migrating before and it stalled.

Stalls usually come from hidden dependencies or no tested cutover plan. The mobilize step addresses that with dependency mapping, runbooks and a pilot wave.

Why it matters nowThe numbers behind this
86%of organizations surveyed are actively reducing their VMware footprint (Source: CloudBolt Software survey of 302 North American IT decision-makers, published February 2026)
69%reduction in unplanned downtime is what AWS reports for its customers moving from on-premises; this is AWS's own figure, not a Kalosys result (Source: AWS Migration Acceleration Program, AWS-reported, accessed October 2026)
