xCode upgrade missing simulators. How can I use locally stored simulators?

Question

I've faces this problem a lot of times that whenever I do an upgrade to xCode. It deletes my old Simulators and I've to download them again. Can any one let any other process. That probably to copy old simulator folders and paste them to xCode contents/Developer/Platform/.....

Or is there any process to add simulators in xCode stored locally rather than downloading them again n again.

There's an interesting answer on the Apple developer forums:

In Xcode the Window menu, select "Devices", also includes a list of Simulators. You can Add "+" ones that are not there.

That fixed things for my Xcode 7.1 beta (7B60)
