You have maps on a 10G APIM. This will need to be removed before you can do anything else. There is no free space to even process an upgrade or change.
Unfortunately you have a MY20+ APIM, which means you cannot reformat the unit with the Syn3Updater process. You will need to go over to FMods ad use their procedure to delete the files and upgrade the unit. If you are not up to that, you’ll likely need to replace the unit in order to upgrade.
