I have an exchange 2010 server (virtual server Hyper-v) set up with only a C drive containing the database and log files, etc. I now have a new exchange 2013 server that i would like to move users to so i can decommission the old 2010 server. The new server has a C drive (exchange OS) and a D drive (for databases and log files). Since the original server only has a C drive i am having problems creating a new database or log file on the new server because the drive letters don't match the 2010 server. So...without having to do too much changing....can i add a couple of drives to the old server (create a D drive) and move the database and log file there somehow? Then i can keep my new exchange server and begin adding new databases to it so i can eventually moves users there. Hope this all makes sense and someone can help with a step by step to accomplish this. Thanks so much!!
