Hi,
I have Exchange 2010 with Sp3 Currently running in environment, Now we have plan to Migrate it to Exchange 2013.... Total number of mailbox is around 26000.
Before Migration we want below things to keep in mind...
1. We want to Use existing exchange 2010 OWA url ( mail.abc.com ), How to accompolish this as it will take couple of months to migrate all mailbox ?
2. Can i use my Existing Exchange certificate to get the above goal done ?
3. What will be the steps and pre-requsite to achieve the Goal ?
An Early reply would be appreciated !!
