Q: I need more migrations! what is the procedure regarding the license?
A: This procedure applies for purchasing/installing another license:
In Plesk, exactly one license key can be installed (resp. active) at a time for each extension. Due to this fact, the 'old' license needs to be terminated first, before you can purchase a new license key for the same extension. It follows that the old license must first be terminated (deactivated) in the Plesk key administrator tool before you can purchase a new license. Don't worry - your 'old' license has been registered on our system, so you will not lose any migrations, even if you terminate the old license before using up all migrations of it.
