Currently there is no way to copy the entire test suite structure from one project to another.
The only two ways of doing it are:
- export + import (never tried)
- create the empty structure in the new project and move/clone the old ones (this is pretty messy as copy/move feature ignores the empty sections and it does not copy the entire structure)
I know there is probably already a feature request like this listed earlier but may I ask the possible ETA of this feature as well as the clone project feature as our company is currently evaluating the software and possibly looking to subscribe/buy TestRail project if it has features suit our needs.
