Planning an operating system upgrade without surprises
Operating systems that have passed end of support quietly accumulate risk. A staged plan makes upgrading routine rather than risky.
Operating system versions reach end of support, after which they no longer receive security fixes. Several widely used enterprise Linux releases have already reached that point.
Why upgrades get postponed
Teams worry about downtime, application compatibility and the effort involved, so upgrades slip.
A staged approach
- Inventory: list servers, operating system versions and the applications they host.
- Assess compatibility: check each application against the target version.
- Rehearse: upgrade a copy of the environment first.
- Schedule: choose windows with the business and plan rollback.
- Verify: confirm services behave as expected afterwards.
Our infrastructure modernisation services cover this planning and execution.
