Can I extend my free trial? (Server)
For server apps, you can extend your app trial up to 5 times - in other words, for up to six months. Extend your trial by generating a new evaluation license key from Atlassian Marketplace. Click Try it free and you'll be directed to generate a new license. Paste this license key into the app listing in UPM from your Atlassian product, and you're all set.
