Best Way to Merge Offline App Forms with Regular Forms Data?

Hi,
I have users who go out into the field without Internet. We need to enable them to enter data into our Forms. Given Zoho restrictions I can't cache Forms for offline access if they have any Deluge scripting anywhere in the Form but in On Validate and On Success (see: https://www.zoho.com/creator/help/application/offline-mobile-access.html)... 

As I have a lot of automation in my Form's Field Actions, I have to create a separate Form specifically to allow offline access. For example, let's say I have Sales Form with all sorts of Deluge logic in it's various Fields like Sales Tax Owing. I have to create a new Offline Sales Form which moves the logic of calculating the Sales Tax Owing into the On Validate Form Action to allow offline caching in the app.

This conversion results in having two Forms holding the same data, how best to merge them into one or prevent having to merge in the first place? Is there a best practice?

Thank you very kindly in advance!
