Hi nathanbaldwin,
Thank you so much for your post. It’s great to hear that you are thinking about upgrading!
If you upgrade in the first 6 months of your license’s valid year, when you upgrade the license will be valid for another full year after the date of upgrade. So when I upgrade a Business license with the expiration date of April 2015, it becomes a Developer license with the expiration date of July 2015.
If you upgrade in the last 6 months of your license’s valid year (as it appears you would be), the license will be valid for another full year after the original expiration date. So if you upgrade a Business license with the expiration date of November 2014, it becomes a Developer license with the expiration date of November 2015.
Does that answer your question? Please let me know if I can elaborate or clarify further. Thank you for your support!
Best,
Leah
