After updating all the categories and attributes go to Catalog > Manage Products and select all the products.
From the mass Action drop-down Select all the products, choose Update Attribute and click Submit button to update all the attributes and categories.
The Update Attribute page will appear. Scroll down to locate Jet Product Status field .
Tick the check-box next to "Change" so that all the products go to Not Uploaded state by default. Now click on Save Button.
