Upgrading Db2 Big SQL

Important: IBM Cloud Pak® for Data Version 4.7 will reach end of support (EOS) on 31 July, 2025. For more information, see the Discontinuance of service announcement for IBM Cloud Pak for Data Version 4.X.

Upgrade to IBM Software Hub Version 5.1 before IBM Cloud Pak for Data Version 4.7 reaches end of support. For more information, see Upgrading IBM Software Hub in the IBM Software Hub Version 5.1 documentation.

An instance administrator can upgrade the Db2® Big SQL service on IBM Cloud Pak for Data.

Important: Starting with Db2 Big SQL 7.2.5, the Hive metastore backend database is the BIGSQL database. The data is stored in the HIVE schema, and accessed by a dedicated system user named hive. Consider the HIVE schema as an internal schema. When the upgrade is completed, its data must not be modified by any locally running workload.
