I'm going to migrate SBS 2000 to SBS 2003 R2. SBS2000 is DC and is running ISA, Exchange Srv and SQL 2000. What I'm really concerned about is really big exchange database. SBS 2003 will be installed from scratch and then migration will be performed. What I'd like to do is making test migraton just to find out if evertything is ok. The question is whether after migration the old server 2000 will be in the same state as before that process.
Did anyone do it before and can share experience?
