This document tells us how to export/import Forms & View for a Guest Registration Process or Import the entire Guest Self-Registration Process configuration.
For this, we need to create a custom backup.
In CP Guest, we need to go to:
Administration > Import Configuration and click Create a Customized Backup.
Select Backup Mode = Custom Backup.
Then check/uncheck what we want to backup (by default, everything is selected).
For Forms and Views:
Select the down arrow next to Guest Manager, then you can drill down to specific forms/views.
This custom backup option can be used to create customer backup for most of the CP Guest options.
