WSE convert to ESE, or ESE to WSE.

Example: Update db2inst1 from V9.1 FP4 WSE to V9.1 FP5 ESE.

- Stop the db2 instance

- As root install V9.1 FP5 ESE to location of your choosing

- Still as root cd to install dir then cd to the "instance" dir

- Run the 'db2iupdt' script from this location

          ./db2iupdt db2inst1



Just as you were able to move up to ESE from WSE, you can move the opposite direction as well (ESE to WSE). It is even possible to move do different fixpak levels as well. For example you can move from DB2 V9.1 FP4 ESE to DB2 V9.1 FP2 WSE using the same general instructions shown above.

Moving from ESE to WSE will likely produce a warning message (DBI1282W), indicating the instance was updated from a higher instance type to a lower instance type. The new instance will use the default configuration settings for the new instance type. Check the values in the new database manager configuration file and update the parameters as required.

DBI1282W  The database manager configuration files could not be merged. The original configuration file was saved as ~/sqllib/backup/db2systm.old (The original instance type is ese. The instance type to be migrated or updated is wse.)

DBI1070I  Program db2iupdt completed successfully.


If you are concerned about your instance settings, it may be a good idea to back up your configurations before any instance updating. You can export (and import) your configuration settings using the db2cfexp and db2cfimp tools: Here are more detailed steps:
