Issues upgrading to v15.5

[Knarin]

Hi,

I am attempting to upgrade a v14.49169.513 PBX up to v15.5.

The install process appears to work correctly and I select to install from my v14 backup. It seems to pull the license key from the backup okay (which then proceeds to tell me it is for an older version. This is no issue as I am installing with a new license key and FQDN).

However once the install is completed nothing has been recovered from the backup, no extensions/SIP trunks/Ring groups etc.

When I point the Backup and Restore UI to the directory which holds the backups it is unable to see any of my v14 backups and thus not restore from them. The UI is able to see any v15 backups I create though.

Does anyone have any ideas or advise on what path I can investigate to resolve this issue?

Thanks.

Perhaps your license key doesn't have active maintenance?

Should that effect v15.5's ability to see v14 backups? I can't see the backups using another client's v15.5 PBX.

Hello @Knarin

Please note that you can only restore a V14 backup during the installation process as there are many differences between V14 and V15.5 that the installer needs to sort out. This means that after the installation is finished you cannot restore a V14 backup.
Do you still have the V14 installation? If so i would recommend going to the licence section of the PBX and changing a single digit of the licence and applying the settings. This will revert the V14 PBX to free and remove the licence. Create a new backup that will not include the licence and proceed with re-installing V15.5.
Let us know if that works for you
