Dude, have you seen how I answered my own question there?
Try doing the same.
“I registered a perpetual license of JUCE 4, can I upgrade to JUCE 5?”
Yes, the upgrade to JUCE 5 for owners of a perpetual JUCE 4 license is discounted by 30%. For JUCE 4 users upgrading to JUCE 5 Indie costs $490, and upgrading to JUCE 5 Pro costs $910. Contact the sales team to upgrade (sales@juce.com)."
Yes that’s correct, there’s no upgrade price as such for monthly subscribers.
However, customers on a monthly license used to pay $49.95, and they will have to choose between Indie ($35) and Pro($65). We’ll adjust that manually and are inviting customers to contact us to adjust their subscriptions.
