I am needing to migrate data from a failing nw6.5.5 server to new hardware. This server is currently a Master Replica. Would it be wise to take the replica off this server and assign it to another server before the migration to minimize problems during the migration, Then add the replica back when finished? Or should I leave it as is? And if I am on eDir 8.7.3 and the destination server is going to be eDir 8.8SP2, I would need to load SP7 on the Source Server?
