Hi, I have to upgrade 2 different samba AD DC (2 domains) from 4.4.5 to 4.10.7 First is a single server and updaded with in-place upgrade from 4.4.5 to 4.10.7 and all perfect Second environment I need to add a second dc and also upgrade existing server, and I have some question about how to do this: - join second domain server with 4.10.7 - then make in place upgrade on existing server dc1? reading wiki I'm not sure if rejoin is needed or not, as I have described recently I have update an existing 4.4.5 (also fileserver) with in-place method and all weems to work... About second domain controller I have question bout dns config, reading wiki amb not clear about what is the suggested /etc/resolv.conf on both dc dc1 dc1 ipdc1 dc2 ipdc2 dc2 dc2 ipdc2 dc1 ipdc1 or dc2 dc1 ipdc1 dc2 ipdc2 dc1 dc2 ipdc2 dc1 ipdc1 Thanks!

Hi, Thanks for your information about DNS config. About second server and update, I understand that First I have to transfer role to new added, demote old, and then rejoin and transfer fsmo roles to source server, right? My question is related with demote and transfer FSMO roles, this task are stable and works correct? I'm not clear to demote main server, now with 4.4.5 because no rolback direct in case of failure... Our actual 4.4.5 has multiple cpu problems, added 4vcpus but is an old version with singe process... My question is if adding second server and if will generate many cpu usage to replicate, all day or only during initial sync... to 4.10.7 thanks!
