This is a converter class for your php file. I was unclear if it was a standard plugin or a mu-plugin.
If it's a standard plugin, then you run it in a register_activation_hook( __FILE__, 'myplugin_activate' );
hook.
If it's not, then you need to set a variable and test for it. Something like surbma_data_migrated
with just a boolean.
This is assuming that you're using Redux with surbma as your opt_name.
Also to filter the sections to add more values for each plugin, check the sample config. There's a class in there.
Happy birthday!
