We have close to 30 Form libraries having infopath forms and we would like to move to Nintex forms 2016. But as I have been reading Nintex forms aren't supported in form libraries. Is it so? And if yes what can be the workaround because we would really like to avoid re creating a custom list just for forms. Thank you
Akdas - One thing to keep in mind is that Nintex Forms in its simplest form are just a nice GUI for your list forms. Because Nintex is built on top of SharePoint and they are not built outside of a SharePoint list or library you will need to convert your form libraries into a custom list.
I have done this in a couple different places and what I do is create all my site columns and get the new form going and then use a Nintex workflow to copy the list metadata from the form library to the list because I have a 1-to-1 relationship because I have the same columns.
I don't believe there is any way around it.
As stated above you won't be able to eliminate a custom list completely, but you can utilize content types, in which case if applicable to your situation, you could have multiple forms on a single list.
PS: Nintex Workflow and Forms is an awesome product and once you start using it you might want to start creating custom lists...
