Tip: Changes from many Db2 11 APARs are built-in when you migrate to Db2 13:
- Enhancements from many new-function APARs in Db2 11 are built-in when you migrate to Db2 12. If you do not apply the PTFs for such APARs in Db2 11, plan for these changes to take effect when you migrate to Db2 12.
- Also check for other Db2 11 service-stream APARs for Db2 11 that were available before general availability of Db2 12. 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 12.
