How do you integrate 2 quality center projects. How can I consolidate 3 projects into 1 project? Will I need to edit schemas/workflows?
No. What you should do is create a new project and then using the elements of the other three projects you can copy to the new project. There is no automated way of merging three projects into one new project. The possibility of data corruption and loss of data makes it less than a desirable direction to take.
