I am preparing to upgrade our Exchange Server from 2003 to 2010 and ran the Pre-Deployment Analyzer.
Looking for some advice on the issues it raised...........
Exchange Organization is in mixed mode. Exchange Server 2010 can only be installed once the organization is in native mode.
Q1 - How do I go about changing the Organization to native mode and what could that impact?
Server xxx has not been upgraded to Service Pack 2 or later. Exchange Server 2010 installation will be blocked until this server is upgraded.
Q2 - The Server that its referencing above was decomissioned a long time ago (before I joined this Company) but obviously Exchange still has some references to it. How do I remove references to Servers that no longer exist so that I don't have to worry about this message during the upgrade.
The Active Directory schema will need to be upgraded (via the PrepareSchema switch of the Exchange Server 2010 setup) before Exchange 2010 servers can be installed into the organization.
Q3 - Can I do this ahead of time? What is the risk associated with the schema upgrade?
Thats it! I know, a lot to ask. Hopefully some kind soul will be able to help.
