How to transfer a plugin license
Here are the best steps to ensure a smooth transfer and avoid any complications:
- Backup plugin data (I always say this, just a precaution)
- Deactivate the license on current site
- Activate license on the new site
So basically remember to deactivate on the old site before moving and you’re good to go.
