I would like to upgrade my exchange Exchange 2003 servers with SP1 (based on windows server 2003 operation system)
to SP2 (and meanwhile I will upgrade the operation system to SP1 too).
The exchange is up and running till one and a half year, it stores 400+ users in two divided databases.
The databases were never offline defragemented yet.
The database sizes are: 23,1 GB MDB + 8,03 GB STM and 21,5 MDB + 8,9 GB STM
I would as the following:
Do might I need to check the databases first for consistency?
Is there any harmless method to check the consistency of the health of the databases?
Which would be the best test utility Ese, or Isinteg?
If the test will come out that the database is corrupt, what steps would ne needed?
What type of harm can I have if I am running the offline defragment on a corrupt database?
Anyway is there any need for the offline defrag?
If there would be any problem, and I cannot mount the databases back, but I've done an offline database backup
is it possible to put it back and mount it without any problem?
When doing offline defrag, all the exchange services should be stopped?
Sorry for the much questions, but I wants to be ensure the success...
