Hi All.
I went to Upgrade from exchange 2010 sp3 running on windows 2008 r2 to exchange 2013 running on windows 2012.
I have the following servers:
1- 2 server running windows 2008 r2 with exchange 2010 sp3 with HUB - CAS role.
2- 2 server running windows 2008 r2 with exchange 2010 sp3 with MBX role.
3- 2 server running windows 2008 r2 with exchange 2010 sp3 with Edg role.
4- storage holding mailbox databases.
what is the best scenario and the upgrade step by step ?
