Hi @AdrienMDesign,
The switch between X to PRO should be seamless, given that your X and PRO version is in the same timeline, my personal rule of thumb here is to make sure my X theme is in the latest version, then I will switch to PRO’s latest version as well.
Always remember to clear all your caching features (plugin, server-side, CDN, and browser’s cache) after updating so that the code from the latest release is always in use. This will help you to avoid any potential errors.
Another thing, if you have customization done on your x-child theme, you need to install a pro-child theme and transfer all your modifications in there.
Hi Ricard,
You can follow the same principle above about switching from X to PRO.
You already have the PRO Unlimited license, you can simply revoke the site using X, Install PRO on that site and revalidate it using your PRO Unlimited license.
Hope this shed some lights,
Cheers!
