Want to upgrade RM Server and Agents from 5.1.1 to 5.2.1

Environment:
RM Server - 5.1.1 with SE 6.4.1
RM Agents - 5.1.1 with SE 6.4.x

Do we need to upgrade our Licenses (LAC) when we upgrade
from 5.1.1 to 5.2.1?

I was reading the RM Support Matrix and it shows on page 9...
EMC RM Manager 5.2 supports SE 6.5.2, 6.5.3, 7.0
I am assuming this also holds true for RM 5.2.1?
I know RM is very particular to the type of SE run on the server.

It also shows in the RM Support Matrix on page 9...
RM 5.2 Server supports RM 5.1.x agents
Is this also true for 5.2.1?

If this is the case, I can go ahead and upgrade the RM Server and not have to rush the agent updates because Replication Manager jobs will still function.


I appreciate any insight I can get
