Currently our office has a 2003 active directory server and a 2003 exchange server. What we would like to do is import the current email accounts on the 2003 exchange server to exchange online. Then we would upgrade the 2003 active directory server to 2012 and link it to office 365 using the directory synchronization.
Now my question is do we need to import the exchange server first then connect the active directory server or the other way around?
