Can I use the same provision profile and distribution certificate for two Titanium Alloy projects

Can I use the same provision profile and distribution certificate for two projects built in Appcelerator Titanium Studio ?

The two projects are actually same so have the same AppID.

The reason for creating two projects is : while trying to do an upgrade to my existing app in Apple App Store the webView stopped working. As a workaround when I created a new project the and copy pasted the same code the webView started working.

So will I be able to use my existing distribution and provision profile certificates to push the upgrade (new Project in Titanium Studio) to AppStore?

Other details : CLI version 3.4.2, Titanium SDK version 3.5.1.GA, Mac OS X, Version=10.10

Thanks in advance Bably
