Be advised that after installing SP3 on Mailbox servers, the databases are upgraded to the SP3 version database schema. An SP3 database can’t be mounted on pre-SP3 Mailbox servers. Keep this in mind when upgrading your DAG (you will temporarily have limited fail-over/fall-back or switch-over options) or for example when utilizing database portability. Note that upgrading databases can be time consuming, especially with RTM or low SP databases as the database will be upgrade using interim steps, i.e. RTM to SP1, SP1 to SP2 and finally SP2 to SP3.
