First i'm a newbie in Plesk. After migration from 8.6 to 8.6 i get some strange issues: 1. Domains that was belong to 1 Client move to other Client. ** just some domains ** 2. I run on this server CMS system that have the possibility to create websites. this system create for each website DataBase and FTP login. the problem now is that the admin of the websites can't modify nothing on them sites because they get error about they cant login to FTP. something like that "Invalid ftp login for www.XXXX.com". 3. when i connect to FTP or SSH i see that some Files/Folders Owners get owners of another site. What mistake we did in migration process?
