Uninstalling or updating the WebSphere V6.1 test environment using Installation Manager; Update Failed.

If you try to update your WebSphere Process Server Unit Test Server from 6.1 to 6.1.2, you may run into an error. This can occur because updates have been applied to the server outside of Installation manager. Basically, WID’s Installation Manager and WPS’s Update Manager are out of sync with each other. This document explains how to fix the problem.

It is also noted that this synchronization issue is fixed in 6.1.2.1.

As usual, ensure you read the appropriate update documentation before attempting any upgrades.
