Siebel Database Upgrade Guide for DB2 for z/OS > Planning a Siebel Database Upgrade >
Upgrading Your DB2 Software
Upgrades: All upgrades. Environments: Development environment only. Before you upgrade, use the Certifications tab on My Oracle Support to verify that you are using currently supported versions of the following DB2 software:
- DB2 for z/OS. If you are using an earlier version of DB2 for z/OS than the versions currently supported, you must migrate to a supported version before you upgrade to the current release of Siebel CRM.
- DB2 Connect. Siebel Developer Web Clients (Siebel Mobile Web Client in connected mode) and Siebel Servers communicate with DB2 for z/OS through DB2 Connect middleware. Verify that you are using the version of DB2 Connect supported for the current release of Siebel CRM.
