OCS 2007 R2 Enterprise Edition and SQL requirements

I recently completed my first EE installation in a production environment. This was a migration from LCS 2005 SP1, and while LCS is not yet defunct, it so far has been VERY smooth.

This particular install was using a SQL 2005 cluster for the back end as well as the archive databases.

Things to know:

• Only SQL 2005 SP1 and SQL 2008 are supported.
  
• For Archiving, MSMQ and Directory integration are needed.
  

  
  

  Lessons learned:
  

• LCS 2005 didn't require a certificate to work properly at this particular customer. This prevented communications between OCS and LCS users. The choices were to fix this or just speed up the plans. Like I said above… completed :)
