Decommissioning Old Infrastructure Safely
After a migration, the old environment still exists — and switching it off too soon, or leaving it running indefinitely, both carry risks. Decommissioning is the careful process of retiring infrastructure once it is genuinely no longer needed.
This article explains how to do it without nasty surprises.
Why It Matters
- Old systems left running waste money every month.
- Forgotten servers become unpatched security risks.
- Switching off too early can break a hidden dependency.
A Safe Process
- Confirm nothing still depends on the old system.
- Take a final backup and keep it for a defined period.
- Stop the system but retain it briefly before deleting.
- Delete it permanently once you are confident.
- Cancel any associated licences and contracts.
Don't Forget the Data
Decommissioning is also a data-protection matter. We ensure data is securely destroyed where required, and that any records you must retain are preserved elsewhere first.
Frequently Asked Questions
How long should we keep the old environment?
Usually a few weeks after the migration is proven, long enough to surface any hidden dependency before final deletion.
Does switching it off save money immediately?
Yes — retired resources stop billing straight away, which is often a welcome reduction after a migration.
