Please see End of support | Adobe FormsCentral for learn more about the Adobe FormsCentral end of support, and to find out what you can do to prepare for this transition. This document lists some alternatives to Adobe FormsCentral, and includes information about saving your existing data and repurposing your forms for use in Adobe Acrobat.
Formstack is one of the alternative options that Adobe suggests using. We do have a form importer that allows you to instantly build a form from any form URL out there. https://www.formstack.com/features/form-importer This will save you tons of time re-building forms in a new platform.
Hope this helps.
They are WAY to expensive in comparison to what you got here.
If moved to Acrobat will the original URL's to the forms still be active?
Cognito Forms is a free form builder that supports many of the same features that Adobe FormsCentral had - plus you can import all of your forms at once. Check out the importer tool here: Adobe FormsCentral Alternative | Cognito Forms - Free Online Form Builder
