Under "Administration" ➜ "Manage apps" we are able to update the license keys after purchasing a valid license.
My question is; is it possible to add a license key beforehand or should you only enter the key at the day of expiry?
As you can probably tell I am worried that if I enter a new license key too early I will in effect loose some days on the previous license. But I also don't want to wait until the very last second to add a new license.
How does this work? I have never done it before.
