I have created vault with 3,4 Workflow for a company & installed it, Also having same settings available in my laptop, Now it requires to do some changes so i have started to make change in to my laptop first then i have exported the .cex of the vault & import the .cex in to the company system at that time it will not overwrite the workflows which i have created & installed in the company system, For Example Workflow with name "Design" is the existing & when i have imported the .cex it will come up with the "Design (2)", So is it possible to overwrite a workflow ?
