You need to create a new project and add it to your evars of the project you are wanting to copy. Make sure delete all the files in your new project 000 folder first.
I did like that but now it throwing following error
PROJECT-CREATION-ERROR-3.JPG
there are no users login existing project.
Only SYSTEM user is logged in.
Anyhave....Try once again after expunging All users( Make sure that No user is working) ....I Replicated many projects by following the above procedure, I didn't got any failures till now.
