WebSphere Application Server migration shows errors and fails if installed features do not match
 Technote (troubleshooting)
 
Problem(Abstract)
Migration of IBM® WebSphere® Application Server V5.0.2 to V5.1 will show errors and may fail completely if the installed feature sets for WebSphere Application Server do not match.
 
Cause
Migration from WebSphere Application Server V5.0.2 to WebSphere Application Server V5.1 involves copying and moving the configuration and applications from one version of WebSphere Application Server to the newer version by using the migration scripts: WASPreUpgrade and WASPostUpgrade. Migration overwrites the existing configuration with the migrated configuration. If the WebSphere Application Server systems being migrated do not have similar features installed, errors will occur and the migration may fail.
 
Resolving the problem
Migration of WebSphere Application Server should be between like systems. Meaning if you have WebSphere Application Server V5.0.2 embedded messaging installed, then the WebSphere Application Server instance you are migrating to should have WebSphere Application Server V5.1 embedded messaging installed. If you have WebSphere Application Server V5.0.2 Enterprise Edition installed, then you should have WebSphere Application Server V5.1 WebSphere Business Integration Server Foundation installed. Update WebSphere Application Server V5.1 to the latest build before running the migration scripts.
Review: IBM - Recommended Updates for WebSphere Application Server Base and Network Deployment editions to determine the latest updates available for WebSphere Application Server V5.1.

WebSphere Application Server V5.1 migrations should be performed using the WASPreUpgrade and WASPostUpgrade scripts instead of using the GUI during installation.

Refer to the technote: IBM - Manually migrating V5.0.2 releases of Network Deployment or Base Edition to V5.1.0 releases.
