Posted on 2011-04-20
we are planning for upgrade of our exchange organization from 2003 exchange to 2007 exchange so i wll open few other questions regarding this upgrade but as of now
I want to upgrade my OWA first to 2007 standard edition which is currently running on E2K3 Enterprise edtion with SP2. please let me know
1. can i go with inplace upgrade from E2K3 to E2K7 ?
2. If yes then how and if no then what OS i should install on other server where i will install E2K7 ?
3. What role i will install on new E2K7 server (i believe CAS).
4. and most important, will it works with E2K3 back end servers because upgrade of those will take some more time ?
thank you in advance for your help folks.
