Server migration and clients update

Hi !
I have a server running version 2.4.15 with about twenty clients, both locally and over the internet. The clients are all on version 2.4.11.

I’ll soon be physically replacing the server, and I’d like to take the opportunity to update the UrBackup server to the latest version. Will I be required to update all the clients manually, or will there be no issues with the migration? Of course, I’ve planned to copy the idents onto the new server before bringing it online.

I’m really quite hesitant about doing this replacement.

Anyone to clarify the procedure?
