No, you don't have to un-install 7.1X to install, infact that would be a bad 
thing for your database instnaces.  Instead of an installation utilize the 
'update' option #2 on the first of the menu options.

Launching console mode...
Preprocessing the input. ^M
=====> IBM Installation Manager

Select:
     1. Install - Install software packages
     2. Update - Find and install updates and fixes to installed software 
packages
     3. Modify - Change installed software packages
     4. Roll Back - Revert to an earlier version of installed software packages
     5. Uninstall - Remove installed software packages

Thanks

Do I have to uninstall tsm 7.1.0 before I can install 7.1.1?

Anyone upgraded to TSM 7.1.1 on AIX?  I'm getting the following out of the 
installer:

Loading fixes...
Validating package prerequisites...
.
Finding compatible package groups...


=====> IBM Installation Manager> Install> Location

Incompatible existing package groups:
     1. IBM Tivoli Storage Manager

ERROR: Package IBM Tivoli Storage Manager server is already installed in this 
package group.

Selected group id: "IBM Tivoli Storage Manager"
Selected location: "/opt/tivoli/tsm"
Selected architecture: 64-bit

     B. Back,      C. Cancel
-----> [C] b

While I continue to wait to hear from Tivoli Level II, any ideas on how to get 
the installer to install?
