I will be upgrading the first of 4 NW51/sp8 servers to NW64/sp3, this
weekend. I plan to upgrade my primary server first then wait several
weeks or months before upgrading the others. It contains the master
replica. Should I move the master replica to another server and make this
a R/W before the upgrade, then move it back at a later time? It also is
the time sync source for the other 3 servers. Should I move time sync to
another as well? Thanks.
