2013 exchange question with regards to running with exch 2007
Posted on 2015-02-03
I was wondering if I need to setup the 2 servers to coexist if the plan for the migration is as follows:
Setup the exchange 2013 server then migrate over 5 or so users from the 2007 exch server and let them test for the next 2 days to make sure all is good then migrate the rest of the users starting on Friday and have them all migrated over by the end of the day on Sunday...
So if I dont setup the coexist would this work and would the users that are migrated over to the new exch 2013 server still be able to email the users on the 2007 and vice versa?
