Hi Raj You can go writting .Ps which will update existing list items. Reference : http://www.thesysadminhimself.com/2013/09/sharepoint-start-workflow-all-items-powershell.html

Lets look at this from a two fold approach - You have a newly created workflow that is already deployed. I am assuming the trigger condition is item update. And it is working fine for new items. To run the workflow on the old items you could write a simple CSOM query to update some simple values in the list (for example update the Modified By column to any particular User or update the Modified to current datetime. Hope this helps!

As my knowledge You should create two workflow on same list .
