Hello, thanks in advance for your attention.
I would like to connect existing clients to a new urbackup server. It’s possible to do it without modifying clients installation? I have 60 clients connected and this could take a lot of time.

There is nobody who can help me? 
I can’t advise you but I would think about moving the identity of the old server to the new server or pushing an updated server_idents.txt to each client.
Take a look at I want to use more then one backup server. What do I have to consider?
