Migration/Upgrade advice
We are looking for guidance on what the best method is for us to migrate from our current (Oracle Linux 6.6, Oracle DB version 12.1.0.2.0) databases to NEW servers (I have already created and set up with Oracle Linux 8.6 and Oracle DB version 19.3.0.0.0). I have been looking at article: https://www.oracle.com/a/tech/docs/twp-upgrade-oracle-database-19c.pdf , trying to determine the best plan of action. Some of the PDB's in question are in excess of 500GB.
I was initially considering a "Relocate and Upgrade" for each PDB (https://support.oracle.com/epmos/faces/DocumentDisplay?_afrLoop=213150284752217&id=2771716.1&_afrWindowMode=0&_adf.ctrl-state=17t6i8t6li_4).
