Major version upgrade MySQL 5.7 to major version 8.0 default

Question

Hello Team
I want to upgrade my MySQL database from version 5.7 major to version 8.0 RDS.
I made a two-way attempt.
1. In place upgrade: Modify Cluster not worked
2. Created new Database form Snap shot but not worked
Can someone assist me with this?

Answer

Hello,

Please check recent events for your instance you will see messages related to upgrade, it is possible that you see events related to failure of PrePatchCompatibility checks.

Viewing Amazon RDS events

Please follow below article to download and diagnose the PrePatchCompatibility log file, resolve the raised errors and then you could proceed with upgrade.
