Key transitions can affect certificate checks, application recognition and server integrity policy as well as publication.
Evaluation approach
Define where old and new signatures are valid. Check supplier configuration and platform support together.
Application example
The newly signed application should retain legitimate account access while unknown signers remain rejected.
Limits and considerations
Accepting all historical certificates indefinitely can weaken the transition.
When should the server retire an old key?
Relate acceptance to platform support and deployed versions. Define a controlled window and end-of-support plan instead of indefinite equivalence.
Checks and decisions
- Build a transition matrix
- Update server expectations
- Test old releases
