I'm going to deploy a new EM 13.5 environment and according the “Cloud Control Basic Installation Guide - 13c Release 5” Oracle Database 19c PDB instance repository requires Oracle Database 19.5 and one-off patch 31145525.
Can I upgrade the Oracle Database to 19.12 release update after install EM 13.5 and create the EM repository in a PDB instance on Oracle Database 19.5?
