Exchange 2007 to Exchange 2010 juggling act.
Posted on 2010-08-16
We are very excited about the new option to archive SMS on Exchange 2010, and would like to upgrade our current Exchange 2007 server.
Where we are kinda breaking the norm. is that we want to still use the same server as it's one of beefiest spec'ed systems we own. We do have other hardware available, but nothing as powerful or with as much RAM as our current Exchange system. I've also been told we don't have a budget for spec'ing out all new hardware at this time.
What my thoughts are....bring one of our extra systems up as a new exchange server, migrate all the primary roles to this server, and then kill off our big server. Format, reinstall OS, and then install Exchange, again, migrate all the rolls back to our main server, and then kill off the "extra hardware" system.
I know this would have to be done over the course of a few days to a week or so to let everything sync up, and also to check for errors that might be cropping up in the event logs between each step...
My question for you guys is....is this a doable "Upgrade path" for keeping the same server running as our Exchange server in the end...
and....should our "extra hardware" system first match, with Exchange 2007, and then let our beefy system be the first Exchange 2010 system...or should the "Extra hardware" just start the Exchange 2010 upgrade?
thanks....Please ask any clarity questions you might need to ask...as I know this upgrade is a bit "out side of the box"
