Migration elastix 2.5 to Freepbx 15

Hello, i have same problem to migration config from Elastix 2.5.0 13.
On Elastix from GUI i made a full backup.
Install new FreePBX server 15.0.16.81
Open GUI > Backup&Restore > Restore> load my backup from Elastix > Run Restore …
It’s after restore:

Running with: /usr/sbin/fwconsole backup --restore=’/var/spool/asterisk/backup/uploads/elastixbackup-20201224144606-o6.tar’ --transaction=‘c440e0ea-4b11-4617-91f2-3f424986b38f’
