Hello, I have 2 windows plesk servers, one has plesk 9.2.3 (with Plesk migration agent & manager installed) and the second is a new one with Plesk 9.5.2 , I want to migrate all data/accounts from the old server to the new. So I login to plesk, and go to Migration Manager , I do complete all the settings and when I press Next button I get always the same error: Error: No migration agents found. Data migration is not available. why is this happening? should I open some specific ports to firewall or something ?
