We are planning to migrate from Ex 2003 Ent to Exchange 2010 Standard SP1
I am currently getting quotes for licenses and CALs.
We have an Exchange 2003 active-passive cluster for HA.
I have noticed that Exchange 2010 brings something new named Mailbox Resiliency which include a set of features for HA.
I am trying to figure out the number of Exchange 2010 Standard licenses that we need in order to keep the same type of HA solution that we have with Exchange 2003 (active-passive cluster).
I am assuming that with Mailbox Resiliency no matter which path you choose you are going to have a minimun of 2 servers (2 Ex 2010 lic) in order to implmenet HA.
Could someone let me know if that is correct?
