Server to server communication

Hello,
 
In AIX Installation Guide 5.3, 
http://publibfp.boulder.ibm.com/epubs/pdf/c3215970.pdf 
<http://publibfp.boulder.ibm.com/epubs/pdf/c3215970.pdf> , under Compatibility 
with Other Versions of IBM Tivoli Storage Manager it states that: "When 
upgrading multiple servers participating in server-to-server to Version 5.3, 
all servers must be upgraded at the same time.".
 
We have 4 AIX TSM (5.1.9.3) servers that participate in server to server 
communication. Two main TSM servers hosts 2 or more TSM instances and each 
database is about 160GB. The two other TSM servers also host Content Manager 
and Common Store that needs to be upgraded at the same time as the TSM servers.
 
Are we forced to upgrade everything at the same time to be in a supported 
configuration. Or does TSM support server to server communication between 5.1.9 
<--> 5.3.1 or 5.3.2? Maybe I need to take a temporary step to 5.2.4 or 5.2.5 
before I upgrade to 5.3.2?
 
Regards,
Henrik
 
 
Med vänlig hälsning
