Hi
​
You can't import your CF5 forms in CF7 Forms.
You have to rewrite all your forms.

Hi,
​
I don't think Colnem is strictly correct - you can backup your CFv5 forms and restore them in CFv7. You can't do that for CFv6 forms though.

Hi Greyhead
​
I never use CF5. But CF7 is fully different that previous version. So I think - but not sure - that I'm wright.
Why many users can't import their CF5 backup?
Have you try to import a CF5 backup in CF7?
​
Please, send me a CF5 form by private message and I'll try.
​
Thanks

Hi
​
With the help of Greyhead, we have do some tests:
​
You can restore a CF5backup in Joomla 3+CF7. Save your backup and restore in Joomla 4+CF7 (try with J4+PHP8). It's good.
But you can't restore a CF5 backup directly in Joomla 4+CF7, neither PHP 7.4, nor PHP 8.
​
Thanks to Greyhead
