Upgrade from previous version of Furniture Store

Hi,
I have been running my website for about 18 months using the previous version of Furniture Store for 1.5. I would now like to upgrade to your latest avaible version for 2.5. Do I have to purchase a new template or will you provide the new version for me? Will I be able to upgrade my website to the new version without losing any of my extensions or add ons?
Thank you

I'am not sure how you bought template , login in commercial downloads and see if you have 2.5 version listed as available download , if not you need to purchase it.
