Problems copying configuration on RUT956 routers

I have two batches of RUT956 routers.
200 units are currently in operation, and I need to add 30 more. I’ve already purchased them, but when I try to copy the configuration, I get an incompatibility error.
I’ve tried with the same firmware version, 07.16.3, and the latest, 07.19.4.
I’ve attached screenshots so you can see the differences.

Router failing to update configuration

Router from which the backup configuration was downloaded

They’re different product codes, hence why the config is not directly transferable.

Hello,

As @Mike has already suggested, backups can only be uploaded on the exact same devices (model, product code, preferably firmware as well, although you are able to upload when there is a firmware difference, though that can cause potential issues).

Regards,
