Hello,
I am planning the upgrade from a 2003 domain to 2012, but I have an old exchange 2003 server not being used, as I have fully migrated to office365 - with cutover migration (No hybrid deployment).
1. Can I simply turn off the exchange server?
2. If I decommission the exchange server, I assume that all exchange attributes are removed, if so, does this create an issue with upgrading domain to 2012 after? or using DirSync with password sync for office365 later?
Thank you for any input.
