Migration utility troubleshooting tips
If you are encounter problems migrating an application from a previous version of WAS to V5...
- Look for these log files and browse them for clues...
- $WAS_HOME/logs/WASPostUpgrade.time stamp.log
- migration_backup_dir/WASPreUpgrade.time stamp.log
- $WAS_HOME/logs/clientupgrade.time stamp.log
Look for MIGR0259I: Completed successfully or MIGR0271W... Completed with warnings in the migration_backup_dir/WASPreUpgrade.time stamp.log, migration_backup_dir/WASPreUpgrade.time stamp.log, or $WAS_HOME/logs/clientupgrade.time stamp.log.

- If the object a client needs to access does not appear, use the administrative console to verify that...
