PRGZ-01225
Source database for non-CDB to PDB conversion had version {0} of Oracle Application Express (APEX) installed and target database had no APEX installed.
Cause
An attempt to migrate a database with non-CDB to PDB conversion was rejected because the source database had APEX installed and the target database had no APEX installed.
Action
Ensure that either source database has no APEX installation or that target database has the same version of APEX installed and then retry the operation.
