Additional Steps for ZDO
This section deals with some steps to be considered in addition to the standard update procedure using SUM.
Interpreting the Results of the Impact Analysis
This step is essential and must not be skipped. If you ignore the results, a serious business impact on production can occur if unchecked business-relevant tables are set to read-only For more information, see Impact Analysis at a Glance.
Functional Validation During the Bridge Runtime on a Non-Productive System
We recommend testing all business processes that must be available for daily operation on the bridge subsystem. For this, the source release must be validated again. Compared to standard upgrades, where only the target release is tested, the test effort can increase significantly.
Considering Load Verification
As with the functional validation, it is recommended to trigger a load check in a non-productive system during the time when users are working on the bridge subsystem. From the upgrade tool perspective, there is no requirement to have real users in the system. The load can also be generated with any load generation and test tool.
