I want to migrate my application (e.g., database migration) from CentOS8 to RHEL9.

Is it possible?

If your attachments are not stored in database, you have to copy them from your old server to the new one

Hello,

Thank you so much!

May I check if there's anything I need to take note of? (e.g., kernel version)

Thank you!

Requirements are documented in Admin Guide and checked during installation

Hi,

Thank you!
