I have a retail (not free) 15.5 install in Debian. I'm "moving" to a Win10 Pro machine. Are the instructions in this post from 2015 still accurate for "moving" my retail license from one install to another? https://www.3cx.com/community/threads/how-activate-my-license.53901/#post-221132 Especially, is it correct to exclude the "License Key Information & FQDN" from the backup which I will use to restore the general config? The old Debian install will be deleted and the FQDN on the new system will be the same as in the current paid license.
