Looking for someone to upgrade existing site from osCommerce v2.2-MS2 to v2.3.4.
Need to keep same functionality, addons, photos, categories, layout, design, etc. as it is and all databases like customers, orders etc.
Can provide all site files & database or can work directly on our alternate server.
Would need to coordinate a time for upgrading database so that any new orders/customers from live site would be included in new version when goes live.
