I've been away from this list for a while but am back into NBU once
again.  I had upgraded a previous environment to 4.5 but it had only one
master server and no additional media servers, so the interoperability
between versions was never an issue.

Now I'm in an environment with many masters and media servers and find
myself as tier 3 for them.  So once again I stand next to the abyss.

I just finished reading the upgrade doc's for 4.5_FP3 and a line jumped
out at me; "This version of NetBackup supports mixed versions between
master and media servers."  I know that 4.5 was supposed to be the
version that allowed all media and masters to work with varying versions
*post* 4.5.  But what I'm reading so far makes me think that FP3 changed
that rule and now 4.5_FP3 will interoperate with media servers at 3.4.1.

Am I reading this wrong?

Thanks.
