Moving from MariaDB 10.2 to 10.11 on Windows OS

I am new to MariaDB and need to move the MariaDB 10.2 files on a Windows 2012 server to a Windows 2022 server running 10.11. Can the file be moved to the new server or do I need to upgrade the old version first.

Answer Answered by Daniel Black in this comment.

Provided the 10.11 service on Windows Server 2022 is stopped, copying all the files from the stopped 10.2 service on Windows 2012 is a good way to upgrade.

Before copying ensure that the shutdown on 10.2 was clean in the Windows Event Log and didn't end in a crash and ends in "Shutdown complete".

No need to upgrade the old version first.

Run mariadb-upgrade after the 10.11 service is started.
