This is how we did our v5->v6 migration, with the exception that we
actually did fresh backups for some of our larger clients due to the
amount of time required to run EXPORT NODE. Basically our procedure was:

1. Stand up a new TSM server as a library client to the old one (with
all the requisite pathing/zoning)
2. For the small clients
2a. Use EXPORT NODE from the old server to the new server
2b. Delete the backup data entirely from the old server
2c. Switch the servername stanza on the client to point at the new server
3. For the big clients
3a. Run incremental backups to the new server
3b. Configure day-to-day backups to point to the new server, while
leaving a servername definition pointing to the old server in case we
need restores
3c. Using some sed/awk magic on QUERY BACKUP output, delete the active
versions of the backups on the old server, then expire the new active
versions (DELETE BACKUP deletes the active version and then promotes the
latest inactive version to be active, and then the EXPIRE makes the
active version inactive again)
3d. Use EXPORT NODE on the archive data if applicable
4. Keep the old TSM server around until the last of the backup data expired

Hi fello TSM'ers,

I need the advice of my fellow Backup admins :)

With TSM 5.5 nearing EOL support and my customer going the Exchange 2010 the 
hand has finally been forced to go with TSM 6.x

My current setup;
Server: w2k3
TSM version 5.5.6 - I have about 60 servers being backed all windows based. 
Quite a bit of historical data going back 7 years for my yearly backups.

I would like to know how best to approach this upgrade?


1.       What I am thinking is to build a new 2008 R2 server.

2.       Do a fresh 6.3.3 TSM install

3.       Export the dev/config files

4.       Export the nodes

The above might be incorrect as I am still exploring options.

Or should I be looking at Migrating TSM 5.5 onto a new 2008 R2 server and then 
upgrading from there. I am looking at the shortest possible way of achieving 
this.

Regards,

Jerome Swartz
