Upgrading from XG450 to XG550

Hi Corporate IT,

Thank you for reaching out to the Community! 

According to the following KBA, You can do a backup-restore from an appliance with an equal or lower number of interfaces(XG450) to an appliance with an equal or higher number of interfaces(XG550) but not the other way around.

Thanks,

PS: Just to be sure: Since V18.0 MR3, there is a new SSMK password in Place. You need this password to restore the Backup. Be sure you have this password at hand or reset this, if you are using V18.0 MR3 and are unsure about the password.
