hello, we will be moving an existing exchange 2003 server to new hardware soon. My question is regarding the DST patches. We applied the os and exchange fixes to the current server along with the mailbox calendar fix earlier this year. What do we do after we move everything to the new server - will we have to reapply the os and exchange and calendar patches? What will happen to everyones calendars? Aren't they going to get all screwed up? Thanks for any help.

I would suggest to test this in a test environment Create a test server from image (exchange and DC) in production if possible Install a new server with Exchange setup /disasterrecover on a server with same name Make sure that all patches are applied Move DBs to new server Start Exchange Deli
