Export everything and Import

Hello,
I setup a new Installation of Mautic 3 to test it. My live environment is mautic 2.15

It is possible to export EVERYTHING from mautic 2.15 (leads, campagins, submissions, etc…) and import them in my new installation?

thanks!

I don’t think you can export campaigns in mautic, why not try cloning your mautic installation to a staging server, I believe that would be the best way to test new installation

This article will get you in the direction:

I tried upgrading to Mautic 2.16.3 first but my forms stopped working, they were all stuck to “please wait”.
I tried all the solutions as clearing cache, disable CORS restriction, etc…but nothing works
I got a cross origin error in my console
