Can I safely upgrade secondary(not main)domino server from 8.5.1 to 8.5.2, leaving main domino directory server in 8.5.1 version ?
Subject: Be aware of the SMTP bug in Domino 8.5.2
If you’re not aware there’s a bug in the SMTP task on the 8.5.2 Domino release.
More information is available here:
Subject: yes
Yes you can.
the new design on your templates (incl DD) will replicate to the other servers (if you have not disabled that) in your domain but I see no problem with that.
Good Luck
