Well let me just say that I've now found new respect for Admins in large businesses that have to install and manage Exchange 2003 - What a PIG, this is the first place where I've had the responsibility of managing Exchange.

Could the steps and time involved be increased anymore - jeesh!

Only have 156 accounts on a 5.5 Exchange implementation. I've just spent the past 7 hours going through steps and pre-checks, and schema changes and replications, etc...
Then installed SP2 - all is up and running, but that is just the start. Have to then start migrating the users and public folders later on.

Boy, I was thinking maybe 3 or 4 hours it would be all up and running - took almost twice that long and I didn't have any DNS or other issues as some Admins seem to have from reports on Exchange.org site.

I can see where a large site could spend the entire weekend trying to do an upgrade. Installing AD was much easier

Oh well, guess now it's time to start learning how to use this new version.
