About the same as almost any migration from one OS to another:

You cannot just move the db volumes from one OS to another OS. The file
structures between AIX (JFS or JFS2) is not recognized by Solaris.

The best way to move a TSM server's contents from AIX to Solaris is to:

1. Build the Solaris server and attach it to its own library.
2. Point all TSM client to the new server.
3. Keep the data on the old TSM server online so that file restores can
be done, and the data can expire over time.
4. When the old server's data has had time to significantly expire,
perform a series of EXPORT NODE commands to move what data is left to
the new server.

The longer the old server is allow to lose data due to expiration, the
shorter the export will be.
