Copy configuration on new boot location after software upgrade from 11.6 to 12.1.1

The config will copy itself over and "convert" on first reboot.

The option "Activate from a different partition" (I think its worded as) refers to if you want to copy a config from a different partitions other than one you're currently in.

Yes, exactly. Looks like this is an option. Install configuration "Yes" or "No"

Thanks again!

Select No - it'll boot with the config from the current active partition...
