Migrations and upgrades
Moving to new hardware, another provider or a newer OS release — with a way back.
A migration is mostly an exercise in preparation. The copying takes an hour; knowing exactly what runs and what it depends on takes the rest.
How it runs:
- Inventory of services, dependencies and cron jobs
- Trial migration to a test environment, including a measurement of real downtime
- A runbook per step, with a rollback plan that has itself been tested
- Execution in an agreed window, usually outside office hours
- Aftercare: DNS TTL, certificates, mail reputation and monitoring adjusted
The same applies whether you are jumping from an end-of-life distribution to a supported release or moving between providers.
