A code snippet to automatically activate the locally stored license key from the previous eCommerce platform (EDD/WC) with the Freemius SDK

README.md

Description

This extra snippet will check if a license was previously activated, and if it does, will activate it through Freemius in the background.

Usage

• You will need to replace my_fs() with your theme's relevant shortcode.
• You will need to rename the function my_fs_license_key_migration() to a unique name.
• You will need to rename 'my_fs_migrated2fs' to a unique option name.
• You will need to replace my_get_license_key_from_prev_platform_storage() with some logic that fetches the theme's license key.
