I have a Magento shop 18.104.22.168 and I need to migrate to the last stable Magento version with a new template (design). I like this site [url removed, login to view] for design and functionality.
I own Full Page Cache extension and maybe some blocks will need to be hole punched.
Magestore - ShopByBrand
ManaDev - LayeredNavigation
AheadWorks - One Step Checkout, Points & Rewards, Gift Voucher, Better Thank you Page, On Sale, RMA, Blog, Help Desk ultimate, Iphone theme 2
Mirasvit - Sphinx Search ultimate
The site is with 100K products, and you can see it here: [url removed, login to view]
All major functions must be migrate to the new version.
