  ****************************************************************
  This APAR must be applied to all members of a data sharing
   group and Db2 12 must be started on all members before one of
   the members can be started with Db2 V13 to migrate the
   Db2 catalog. Non-data sharing Db2 subsystems must also run
   with this APAR on Db2 12 before attempting to migrate to Db2
   V13.
   This APAR allows fallback to Db2 12 after a migration to Db2
   V13 and also allows release coexistence in a data sharing
   environment.
   Refer to the Db2 V13 publications for procedures
   for migration and then subsequent fallback to Db2 12.
  

Problem conclusion

Temporary fix

Comments

• The purpose of this APAR is to allow fallback from Db2 V13
  and release coexistence between Db2 12 and Db2 V13.
  Refer to the chapters 'Falling back' and 'Remigrating'
  in the DB2 V13 Installation Guide for these procedures.
