Larry,
changing the TCP-Port doesn't have any impact on the objects backed up.
As it is still the old filesystem on the old server and the old TSM
client software, you won't see any impact.

TSM sends a list of backed up objects from the TSM server to the client
node. The BAClient checks this list against the real filesystem and
sends the changes (new, updated, deleted) to the server. The TCPPort
doesn't have any influence in this mechanism (I'm glad).

Best regards,
Michael

Hello TSM list,

TSM 5.3.3.0
AIX 5.3.0 ML4

I have a TSM instance that is using the default TCPPort (1500).  I need
to change it to use a new TCPPort.  This will require a coordinated
change on the TSM server and all the clients.  What I want to verify is
that this change will not force a new full backup on all the clients.  I
have not been able to find any documentation that explains the impact of
changing the TCPPort.  Any pointers or experience will be appreciated.

Thank you,
