My scenario is I want to move mailboxes from Exchange 2007 to a new
Exchange 2007 server within our domain. I have 240 mailboxes to move
and some of our users depend on OWA and Outlook Anywhere as well. The
mailboxes I will be moving are large in file size. One mailbox alone is
almost 8GB in data. The challenge is to move the each user mailbox
with no downtime whatsoever.
I already have planned this out by
means of scheduling moving of mailboxes per batch or per department and
on the OWA side, we will just have to allocate another public ip and
point the Second Exchange Server box to that ip so that the users who
are moved to the second exchange server will use the second OWA url
while the others who are still on the primary exchange box use the
existing OWA url. Our network is just running in 10/100 which is why I
am not sure as to how long would it take to move just a single 8GB of
mailbox from one exchange to another exchange server. The primary
Exchange server is a Xeon cpu with 6GB of ram only. I am hoping this
server will not crash during mailbox move most especially the task might
eat up a lot of system resource. Aside from that, it is also running
out of hard drive space as well. The second Exchange server is actually
the same brand and hardware but will have more ram 12GB to 24GB and a
couple of TB drives as well. In addition, I am not sure if the steps
below are exactly what I must do but I would appreciate if someone out
there can provide me all the details I need. Anyway, below are the
steps I am thinking of....
- INSTALL SERVER 2003 on Second Server
- Assign a unique COMPUTER NAME
- Assign PROPER IP
- INSTALL UPDATES
- CONFIGURE DNS
- JOIN SERVER TO THE DOMAIN
- install pre-requistes
- INSTALL EXCHANGE SERVER
- Install Rollup and hotfixes
Copy all Organization Configuration and Server Configuration settings
from Primary Exchange server to Second Exchange server (Mailbox, Client
Access, Hub Transport, Accepted Domains, Send and Receive
- Make sure all storage groups and databases on the Second Exchange Server are configured and mounted.
- Perform a test maibox move from Primary Exch Server to Secondary Exch Server.
After mailbox move, on the users Outlook Client, go to Control Panel
and change mail settings pointing to the Second Exch Server.
- Open Outlook and test if all mails are intact.
next question would be how can I copy the Primary Exch Servers
Distribution Group and Mail Contacts to the Secondary Exch Server? Will
there be any conflicts/problems on both Exchange servers having the
same Distribution Group and Mail Contact content?
amount of mailbox data I need to move, I will have to spend
weeks/months just to be able to move everyone's mailbox. This will
probably have to be performed during weekends unfortunately. I just
want to make sure both Exchange Servers will work on the same domain
until the time all mailboxes are moved. I sure appreciate everyone's
advice. Thank you.
