Chapter 22. Tivoli Storage Manager upgrade considerations
693
Bear in mind that if you upgrade to Tivoli Storage Manager 5.3.x from any
previous release and you have Windows clients that back up their system
objects, you should take specific actions to clean up the orphaned system object
entries in the database, For details see the IBM Support Web site at:

FILE volumes and paths to FILE devices
When the V5.3 server starts, existing FILE volumes in a FILLING state are
marked as full. In V5.2.x and earlier servers, the server accepted a PATH
definition for a local FILE library and FILE drives, although it was not used in any
way. Such definitions are not accepted by a V5.3 server and are rejected. This
could be problematic if these definitions are contained in a devconfig file, and
must be removed manually.
Password length
When the server database is upgraded to V5.3.0 or later, the encryption level of
stored passwords is converted from DES 56-bit to AES 128-bit. During the
conversion, decrypted passwords are checked against the server minimum
password length setting. If a password is shorter than the minimum length, an
invalid password error message is issued and the database upgrade fails.
Passwords shorter than the minimum length can exist if the server's minimum
password length setting has been changed. Changing the setting does not affect
existing passwords. The new password length is only enforced when passwords
are first registered or updated. Any previously created or expired passwords that
do not meet the current length requirement are considered invalid during the
database upgrade.
If there is any possibility that shorter passwords are stored in the server
database, use the following upgrade procedure:
1. Temporarily set the minimum password length to zero (0). To change the
minimum password length, you can use either the Administration Center or
the SET MINPWLENGTH command.
2. Back up the current server database.
3. Install the new version of Tivoli Storage Manager.
4. Reset the minimum password length to the desired value.
Transition version of administrative Web interface
The Administrative Web interface has been replaced with a completely new
Web-based interface called Administration Center. Together with the Integrated
Solution Console (ISC) that provides a framework for Administration Center, you
