Hi Alexander,
Is there any way to copy DFFS Modern forms from one site collection to another if the list column names (internal and external) are identical?
I have 37 lists in one site collection and each has 3 forms and I need those forms in an identical site colleciton with the same 37 lists.
With this many forms I suggest you copy the content from the configuration list directly. This list can be found on this address: /sites/your_site/Lists/DFFSConfigurationList
If you only need to copy a few form config you can use the Import / Export functionality found on menu in the top left corner when editing a configuration.
