Backing up from xg125 and restoring to xg115

Question

Hi guys, 
 I'm having some issues with resotring a backup configuration file from an xg125 to an xg115. Only ports 1 and 2 are used, and both devices are not wireless. Both are on the same firmware version and MR. Is this an issue or is it even possible? 
 Thanks,

Hi @wajdiaa You may refer below "Backup-restore compatibility check" https://community.sophos.com/kb/en-us/124585 You may refer Note section and you will get hint for your issue. You can do a backup-restore from an appliance with an equal or lower number of interfaces to an appliance with an equal or higher number of interfaces but not the other way around.
