Software Migration.
Move platforms without moving your users.
A platform migration your users don't notice — with parity-verified cutover and a rollback plan for every step.
What it is
The best migration is the one your users don't notice happened.
Software Migration is careful, staged, reversible work — moving a product from one platform, framework, database, or cloud to another without downtime and without breaking user-facing behaviour.
We use strangler patterns, shadow deploys, and parity tests to migrate one slice at a time. Every step has a rollback plan. Nothing goes to users until parity is verified.
The end state is a modernised platform your team is happy to be on-call for, with a documented migration process you can apply to the next slice yourself.
What you get
6 concrete things, on the SOW.
Every deliverable is written into the statement of work — priced, dated, and signed off by a named engineer at the relevant gate.
- 01Full migration plan with rollback per stage
- 02Parity test suite (behaviour-verified)
- 03Shadow deploys, progressive rollout
- 04Data migration with reconciliation
- 05Legacy decommission runbook
- 06Post-migration performance baseline
Where this shows up
Three shapes of engagement.
Different problems, same method. These are the concrete work shapes we typically deliver under Software Migration.
Cloud migration
On-prem to cloud, or one cloud to another, with data and infrastructure parity.
Framework upgrade
Move off an unsupported framework major version without stopping feature work.
Database migration
Move databases (or database engines) with row-level parity and zero downtime.
The stack
Capabilities, not vendors.
The requirement picks the tool, not the other way round. Naming vendors up front would set the wrong ceiling on what we take on.
- Strangler pattern
- Shadow deploys
- Parity testing
- Data reconciliation
- Progressive rollout
- Feature flags
How it runs
Seven stages. One signature at a time.
Every Software Migration engagement runs through the same seven-gate Aivora Delivery Engine — each stage run by specialised agents, each ending at a gate a senior engineer must sign.
Frequently asked
Questions people ask before booking.
How long does a migration take?
Depends on the surface, but we scope in weekly slices with a defined "done" per slice — never an open-ended "migration project."
What if a slice fails after cutover?
Rollback is one command, and it's tested before cutover. Every slice is reversible without data loss for the rollback window.
Can we do this while shipping features?
Yes — that's the point of strangler-pattern work. Feature teams keep shipping on the legacy; we add new capability alongside and cut over.
