Migrate from WooCommerce API Manager to WP Software License

The WooCommerce API Manager plugin is the first code of its kind available on the market by years now, so it’s widely spread. It had good features and support, still, it was very expensive and integration wasn’t straightforward for everyone. On top of the minuses is always been very slow making it impossible to use on low profile hosting or on medium to large websites with thousands of API calls per day.
The WO Software License plugin is a recent plugin that uses the new WooCommerce features and took a different approach to achieve the functionalities. It’s extremely fast due to its light code and an included cache module which provide outstanding performance for any sites.

Many users prefer to migrate to WP Software License plugin as being more reliable and incomparable lower cost. The following code can be used for that purpose, it translates the old license keys to the new system. Before starting the migration process, the WP Software License plugin should be active and key activated. Also, all products which use licensing should be filled in with appropriate data:

Further, add the following code to domain root:

Before the code run, a database backup is highly recommended to prevent any import issues. Since there are many possible scenarios, rarely there might be pieces of information that apparently do not migrate. In that case, we can help and make adjustments to the code.
