Why Enterprises Choose AppStudio for Application Migration

Migrate Without the Outage

We move applications in phases with a rollback at every step, so the business keeps running instead of betting everything on one big-bang cutover.

The Right Path per App

Each application gets the strategy it deserves, rehost, replatform, or refactor, chosen on cost, risk, and how much value the move actually unlocks, not a blanket approach.

Modernised, Not Just Moved

Migration is a chance to shed technical debt. We right-size, containerise, and tidy dependencies as we go, so you land on something better to run rather than just somewhere new.

Proven Before Cutover

Every migration is tested against real data and load, with parallel runs and reconciliation, before we ever flip production over.

How We Plan and Run Your Migration

A migration succeeds or fails before the first workload moves, in the assessment. At AppStudio we map dependencies and risks first, then move in waves you can reverse.

This connects to our cloud application development, hybrid cloud services, and software modernization work.

The outcome is applications running better on a modern platform, with the cutover proven rather than hoped.

We catalogue applications, dependencies, and data, and flag the risks and quick wins.

We choose a strategy per application and sequence the moves so low-risk value lands first.

We move in waves, run in parallel, and reconcile data before any production cutover.

We switch production with a rollback ready, then confirm performance and integrity.

We right-size, tune cost, and run the new environment to a defined model.

Why Clients Stay With Us

We are measured on migrations that land cleanly and run better afterward, not on a cutover that merely happened.

Move Off Legacy Without Betting the Business on It

Aging applications rarely fail loudly; they just get slower, riskier, and more expensive to keep alive. A deliberate migration turns that liability into a modern platform your team can build on again.

It works hand in hand with our cloud application development, hybrid cloud services, software modernization, and IT managed services.

Point us at the applications you need to move, and we will map the dependencies, the risks, and a wave plan around them.

Application Modernization Strategy: Patch It or Replace It?

Frequently Asked Questions

It runs from assessment through to a stable new environment: inventorying applications, dependencies, and data, choosing a strategy for each, moving in waves with parallel runs and reconciliation, cutting over with a rollback ready, and then optimising and supporting what has moved. The upfront assessment is where most of the risk is removed, so we never skip it.

On cost, risk, and payoff. Rehosting (lift-and-shift) is fastest and lowest-risk when you need out of a data centre quickly. Replatforming makes targeted changes to use managed services without a rewrite. Refactoring is for applications where re-architecting genuinely unlocks scale or speed. We assess each application and recommend the option that fits, rather than forcing one approach across the estate.

Usually, yes. We use replication, parallel running, and staged cutovers so most of the move happens while the current system stays live, and the final switch is short. The exact downtime depends on data volume and how the application handles state, which we size during the assessment.

Data is migrated with integrity checks, and we reconcile source and target before cutover, so the numbers are proven to match rather than assumed. Where the risk is high we run the old and new systems in parallel and compare, and we keep a rollback path until the new environment is confirmed.

AWS, Azure, and Google Cloud, or across them, as well as on-premises to cloud and between clouds. We set up the landing zone, networking, and identity properly first, and weigh data residency and compliance for each workload rather than assuming everything can go anywhere.

Yes. We handle same-engine moves and engine changes, such as Oracle or SQL Server to PostgreSQL, migrating schema and data with validation and, where needed, replication for minimal-downtime cutover. Engine changes are scoped carefully because they touch application code, not just the data.

Whichever fits your goals. A pure move is faster and lower-risk; modernising along the way, containerising, updating runtimes, adding CI/CD and observability, costs more effort but leaves you with something better to run. We often rehost first for speed, then modernise in a second phase once you are off the old platform.

We migrate in waves rather than all at once, so only a small, controlled slice is in motion at any time, and each wave has a rollback. The business keeps running on the current environment until each piece is proven on the new one.

We plan for it. Every wave has defined rollback points and success criteria agreed in advance, so if a cutover does not meet them we roll back to the known-good state rather than pushing through. That is why we insist on tested rollback before any production switch.

Yes, and it is where a lot of the value is. Once workloads are settled we right-size and tune cost, set up monitoring and a clear run model, and can operate the environment on an ongoing basis, so the migration ends in something well-run rather than handed over and forgotten.

A single application can move in weeks; a large estate runs on a wave plan over months, sequenced so value arrives along the way rather than at one distant finish. The assessment gives you a realistic, wave-by-wave timeline before you commit.

Book a consultation and we will review the applications you want to move, map their dependencies and risks, and lay out a strategy per application with a wave plan, rollback points, and a realistic timeline.
