Tip: Changes from many Db2 12 APARs are built-in when you migrate to Db2 13:
  • Enhancements from many new-function APARs in Db2 12 are built-in when you migrate to Db2 13. If you do not apply the PTFs for such APARs in Db2 12, plan for these changes to take effect when you migrate to Db2 13. See the APARs with availability dates earlier than 2022-06 in New-function APARs for Db2 12.
  • Also check for other Db2 12 service-stream APARs for Db2 12 that were available before general availability of Db2 13. If you did not already complete any required actions that are described in ++HOLD data for these APARs, make plans to do so before migration to Db2 13.
