To move items between products in Sprint.ly, you'll need to be the admin for both products. Once you have verified that you're the admin for both products, locate the product ID of the DESTINATION product. The product ID can be found on your Products page. The Product ID is the set of numbers that follow https://sprint.ly/product/ in your Git Commit Hook.

Now you're ready to move your item. Find the item that you want to move. Click on the gear icon, select "Move to Product" action, enter the destination Product ID number, press enter and you're done!

When you move a story, all sub-items will move with the story. Please note that the history, comments and attachments of the item will not follow to the new product.
