Two part question:
Part 1: on our current 2003 rs dell 1950 (dual core & 12GB ram) We have 120 - 150 network users, about 100 groups, 120 IP phones, running DHCP and DNS for 8 locations and allocating ip's for all 120 plus across these 8 locations. And, a separate exchange 2007 server.
We want to upgrade to a new 2012 AD DC server (dedicated) as well. We are considering between two configurations.
Dell R320 32GB ram one six core processor, raid 1 146 GB drive (mirrored).
the same spec except a Dell R420 with two 6 core processors.
Dell thinks the second is way over kill and the first is more that enough power to handle our user base.
The difference in cost is about $700 ... not so much but silly to spend if it is going to be wasted dollars. Thoughts on this will be greatly appreciated.
Part2: We need to move (migrate) our 2003 AD config and all scripts etc. to the new box.
Should we build from scratch (seems dangerous) or migrate.
How easy or hard is the migration and is there a really good set of instructions or white paper on this?
