Restoring Web Gateway Backup to new Virtual Appliance

We are trying to migrate our existing ageing physical web gateway appliances to two new virtual appliances. We have built a cluster to match the physical clustered appliances and joined the virtual appliances to the domain, configured a few users and imported a signed SSL certificate for SSL scanning. We are now at the stage where we need to restore or import the policies into the new clustered virtual appliances. We have taken a backup of the physical and virtual appliances and attempted to restore the physical backup file to the virtual cluster but we get an error: Restore failed due to following exception: failed to restore backup of sent configuration: cannot find own UUID '[long sequence of characters]' in backup." Is there something we are doing wrong or is there an easier way of achieving this aim please?

Re: Restoring Web Gateway Backup to new Virtual Appliance

Hello @User15471529,

I apologize for the late reply. Probably you have already solved this but still wanted to answer for documentation purpose.

A UUID is system/appliance specific and so is the "Configuration" part of the MWG. Backup includes 2 things, "Policy" and "Configuration" part. Policy part can be easily imported in every other machine while Configuration is linked to the UUID of the appliance where it was taken. So if you import backup to new machine and check the box to include configuration and accounts as well, then it fails because new machine has different UUID.

So a configuration part (all under "Configuration" tab in MWG UI) can only be imported to other machine via CLI where you must run a command which includes the old UUID.

All is described in our best practice guide here:
