The Official SBS Blog : SBS 2008 Migrations from SBS 2003 – Keys to Success:
How the SBSBPA differes from the EBS Prep tools recommended in that post:
SBS BPA checks the health specifically for SBS 2003.
In that list the only item that is specifically going to cause me issues is the Exchange functional level.
In the EBS Health scan tool, the main difference is that the EBS health tool checks for AD replication issus that the SBSBPA may not catch. Then it checks DHCP, DNS, etc but it’s checking general health of the network in potential replication issues.
Thus it’s wise to run BOTH tools when preparing for SBS 2008 migrations.
And one of the first steps that BOTH tools tell you to do in order to migrate to Exchange 2007 is to flip the Exchange server to Native mode.
- Start Exchange System Manager. Click Start, point to Programs, point to Microsoft Exchange, and then click System Manager.
- Right-click the organization, and then click Properties.
- Click the General tab, and then click Change Mode under Change Operations Mode. Click Yes if you are sure that you want to permanently switch the organization’s mode to native mode.
