Template for planning a PHP version upgrade
Structure work from inventory through post-release observation while separating compatibility, functional change and operations.
Complete the resource with evidence, not ideal answers
A checkbox helps when it represents a verified situation and leads to a conversation or decision.
Bring together people who understand product, development and operations. For each section, identify repositories, configuration, metrics, incidents, screenshots or examples that justify the answer. If evidence does not exist, record the uncertainty: it may matter more than completing the checkbox.
At the end, group findings by impact and dependency. Separate immediate controls, required investigation and structural improvements. The result should state what will be done, who can decide it and how it will be verified, avoiding a wish list without priority.
- EvidenceSource or example supporting each answer.
- ImpactConsequence for users, business or operations.
- PriorityOrder based on risk, dependency and effort.
- ActionOwner, boundary and outcome verification.
Inventory
Know the combination actually running.
Protection
Create a reference before change.
Compatibility
Resolve incompatibilities in sequence.
Rehearsal and release
Practice what will happen in production.
Observation
Confirm the system still meets expectations.
Turn answers into decisions
- Assign an owner and exit evidence to every phase.
- Do not mix unrelated improvements into the version change.
- Rehearse rollback with the same care as release.
- Keep a record of decisions and accepted risk.
