Verifying successful migration to Db2 13
After you activate function level 500, you can run the sample applications to verify that your migration process was successful.
Before you begin
Attention:
When migrating from Db2 12, do not run the Db2 13 IVP jobs before activating new function as described in Activating Db2 13 function level 500 or higher. 
For best results, activate function level 501 first. You can also run the IVP jobs at function level 500, but then you must edit the IVP jobs to use the correct APPLCOMPAT level in BIND commands.
Until you complete this task, continue to use sample applications such as DSNTIAUL, DSNTEP2, and DSNTEP4 from Db2 12.
Procedure
To verify successful migration to Db2 13:
Tailor and run jobs for the sample applications, as described in Verifying successful Db2 13 installation or migration with sample applications.
You can select the phases that you need to run based on the attachment facilities you
installed, the languages you use, and whether the sample objects exist.
