The following are a few notes and links that I found useful when performing an Exchange 2010 upgrade for a customer. This is for Phase 1 coexistence of Exchange 2010 with 2003. Phase 2 for decommissioning Exchange 2003 can be found here.
The project also included the introduction of a 2008R2 Domain Controller in a Branch Office alongside their existing 2003 Domain Controllers, and the establishment of a Domain Trust to allow a recently acquired company existing in a different Active Directory forest, to use the new Exchange 2010 server via Linked Mailboxes.
Figure 1: The diagram below gives a brief overview of the environment after introduction of the Exchange 2010 server
Note 1: Exchange 2010 does not support BES 4.1! In the deployment here, Blackberry was being decommissioned, so there was no need to worry about maintaining the Blackberry service by migrating BES to version 5 or above.
Note 2: The customer was using Symantec Backup Exec 11d and this does not support Exchange 2010 – BE 2010 or above is required (but it is possible to Use Windows Server Backup to Perform a Backup of Exchange!)
Main documents used:
1. “Rapid transition guide from Exchange 2003 to Exchange 2010” by Milind Naphade – this PDF document is freely downloadable from the internet
2. Upgrade Exchange 2003 to Exchange 2010 Part 1 and Part 2 by Jaap Wesselius
Useful notes and documents – regards the Exchange work:
Apologies for plugging my own blog with the first three!
