Why do FSMO roles need to be transferred to the destination (New upgrade server) after migration?
our old server is 2003 and working perfect in its box. Apart from the mainstream support that is due to expire 7/13/2010 - I see no reason to decommission this server and leave it till this date as a backup Domain controller.
The migration is complete apart from FSMO role transferral as mentioned. We are running Server 2003 and Server 2012 together which are replicating and I don't want to de - promote 2003 but also don't want to run into any problems by doing so. I just don't understand why standard protocol is to de-promote when you could use it as a backup AD server.
Thanks for any advice
