Backup & restore different XG model

Question

Hello, 
 I have a question about the backup & restore possibility on the XG Firewall. I installed a demo model of a XG210 rev.2 for a custommer in order to test it because this is the only model I could get in demo from my reseller, but the final model to sell will be a XG135 rev.3. I configured the XG210 to work perfectly with the 2 internet fibers providers, ssl vpn, active directory authentication, exchange server protection etc etc... 
 
 And now I wonder if I could backup and restore the config from the XG210 to a XG135 with 100% compatibility or not? 
 
 Thank you for your answer.

You can do a backup-restore from an appliance with equal or lower number of interfaces to an appliance with equal or higher number of interfaces but not the other way around. 
 Flexi ports have no impact on the interface count during the backup-restore process
