instead to upgrade an exstiing UCS PDC + Backup + Slave from 4.9x to version 5.x, I want to setup a new clean DC infrastructure.
However, all existing AD data should be taken over.
That’s why I wanted to set up a backup server (backup directory node) version 5.x first, sync with an existing PDC (version 4.x - if it then takes place) and after switch off the old DC.
The apps (Kopano, Samba, Nextckoud etc.) which are currently running on their own members servers (4.x) should then be gradually taken over.
Does this work or can it lead to various problems and if so, which ?
