General comment: we'll need to handle migration of the existing variables to the new properties system.

Would that be fitting to do in the install file?
Or isn't that used during updates?

[josegonzalez]

Maybe update - can you check what trigger we use in the plugin:update calls? - though we might need to do both - I think plugin:install is more or less plugin:update...

They can be different, plugn calls the install hooks for install and update for update, but with update just being a link to install in this plugin, they really are the same.
