Seems my pfSense plus was RIP by netgate just after 3 months, so need to go back to CE for my lab

is it possible to upgrade 23.05 to 2.7.2?

Note: I bought the TAC lics for my HA cluster, but this box is just for testing purposes.

@planetinse Yes, more or less, because that is going forward in config file versions.

Reinstall CE and restore the config file.

@SteveITS I ended up with another TAC license - but thanks anyway
