Our Email Systems components consist of:
Exchange 2010 Server: EX1 (CAS, HUB, MLBX)
Exchange 2010 server: EX2 (CAS, HUB, MLBX).
Each has 3 Databases USDB1, USDB2 USDB3 and all these databases are in A DAG.
MS TMG server: TMG handles all OWA, Outlook Anywhere, ActiveSync.
Fortimail C100: handles all smpt incoming and outgoing emails.
All of these servers are in main office with about 350 users.
Last year we just opened a collocation Data center about 150 miles from
our office.We have MPLS between office and collocation with The bandwidth is 50Meg.
The questions is how can I move all of my email systems to collocation
without interruption of email flows or users.
Activate all DB in EX1 as active
Move EX2 to Collocation first
Activate all DB in EX2 as active
Move EX1 to Collocation
Change outside DNS for owa...etc
Move TMG to collocation
Change outside MX record
Thank you for your help.
