We are going to apply Oracle patch 126.96.36.199 on Oracle 188.8.131.52. We have 184.108.40.206 patch. We are using (DBUA) for this upgrade. As DBUA will check the preupgrade requisites, we want to run preupgrade check manually.
Could you please help where we can find preupgrade check?
How to run this script?
ORACLE_HOME should we run this script, as we have two ORACLE_HOME directories?
