We are in the process of upgrading our ECC 5 with Oracle 11g running on AIX 5.3 to ECC 6 with EHP4.
During the course, we have executed 3 iterations of the Production copy upgrades and were achieving minimal downtime.
Every time, the System Isolation Steps Before Switch To Downtime Step - Deletion of pending update records In SM13, takes about more than an hour which is a part of technical downtime.
I would request for some ideas of expediting this step. As this would drastically reduce our downtime.
