v15.5 to v16 license upgrade?

[vhi IT]

I just don't recall from the last time how it works and if anything is needed. I have a perpetual pbx license on our v15.5 server with maintenance. If I do a full backup and include license info and then set up the new v16 pbx and restore the backup will my license that was running as v15.5 "self-upgrade"? I just don't want to run into some issue where its a weekend and I upgrade but it won't take my license or activate or something and I am running like 4 simultaneous call limit or something. Can anyone confirm?

Are you running Debian or MS Operating System ?

If Debian what version ?
If MS what version ?

windows server 2012 r2.
I am planning on
-doing a full ZIP backup including license
-uninstalling the v15.5 pbx software
-install new v16 software
-during creation choose to restore backup instead of create new

I have done this on our test pbx but don't recall how it handles the license.

This is the screen I had some across once. so i'm perpetual and in maintenance so it should go through with just a license refresh. Thank you
