I will be using this method to move my v14 installation to the v15.5 What I want to do is install the v15.5 on a new machine, import the backup and when the procedure is finished move the new machine to the office and replace the old one. The two boxes will have the same local ip but everything else is different. Public ip (temporaly until moved to office location), FQDN (will be used a 3CX provided on the v15.5 installation), MAC address. What happens in this situation with the license? Will importing my backup break the old installation? Also when I move the box and replace the old one, is it possible to change easily to the new public ip? Should I import my backup with the dynamic public ip option enabled to avoid changing the ip later?
