@anshulrathi Thanks for your post! I’m not sure I entirely understand your question. Are you hoping to have access to previous versions of your documents for reference? If so, I recommend the Revision History tool, which allows you to view, manage, restore, and copy from previous versions of your board.

If you’re referring to something else, please let me know!

Thanks Micah !! 

That helps !! I am looking for revision history option only !!

I’m glad to hear that! Please let me know if you have any questions about using it.
