Hi There,
We have around 2 Exchange 2010 mailbox server with 5 mailbox DB's on each mailbox servers, for some reasons we are going to add additional no of DB's to it, as of now we are having Exchange servers in standard edition.
I hope we need to upgrade the licence from standard to enterprise as i'm creating more than 5 DB's per server, please someone confirm me the followings, will it be like,
1. Do I need to pay the full money for enterprise edition license?
or
2. Do I need to pay only the extra amount to acquire/upgrade the existing license to Enterprise edition?
I'm worried whether the existing license (Std edition) will be wasted if MS asks me to pay full money.
