Troubleshooting and Support

Solutions to migration problems for V5.1
Browse through common V5.1 migration problems and solutions that have already been documented and published to the Web.

Collecting data (MustGather)
When a solution cannot be found to your migration problem, you can begin collecting data (MustGather) before calling IBM support. This will help you familiarize yourself with the troubleshooting process and save you time.

Exchanging information with IBM Technical Support
To diagnose or identify a problem, it is sometimes necessary to provide Technical Support with data and information from your system. In addition, Technical Support might also need to provide you with tools or utilities to be used in problem determination.

Instructions for handling certain Out of Memory conditions which occur during migration of an earlier version of WebSphere Application Server to V5.1.1, V6.0.2, or V6.1
When running WASPreUpgrade or WASPostUpgrade, during the migration process from an earlier release of Application Server to V5.1.1, V6.0.2, or V6.1, the heap might run out of memory for a complex environment. Either the execution of wsadmin to install the applications, or the migration of the configuration itself, throws java.lang.OutOfMemory errors.
