Help with broken upgrade

How to migrate forms from ChronoForms v4 to v8 after a broken Joomla upgrade.

Overview

The issue occurred because a Joomla upgrade left the site in a broken state, making the CF v4 backend inaccessible and preventing form export.
You must rebuild the forms manually in CF v8, as direct export is not supported. For forms with custom PHP validation, contact ChronoForms support for assistance in recreating the necessary actions.

I have been asked to help with a joomla site that was upgraded. There are now two part broken websites. One has working chronoform 4 forms which recieve data, but the backend is broken so it cant be accessed and the other is joomla 4 and is broken all togethe but I can see logged data.What I would like to do is see if there is an easy way to copy the forms from chronoform 4 database into chronoform 8 database. I am unable to export forms due to the broken nature of it all.I have tried spinning up a joomla 3 site and tried piecing together parts to get chronoform4 installed and then copy the database to create exports, but I cant seem to get a working version of chronoforms 4.Any help would be greatly appreciated.

Hi verse

There is no way to export your v4 forms to v8, you will have to rebuild the forms in v8, which should not be so difficult if the forms are basic ones and you are familiar with how v8 works, here is a tutorial:

Ah ok. The fields are simple in principle, but I believe there seems to be some custom php script for validation and I have no knowledge on how to recreate the actions exactly.

Do you think someone from Chrono Forms would be able to help with this? if so could you reach out with details / rates please.

v8 has many validations available, but if they had custom validations then this will have to be copied to the right place in v8
