How to move a module from package A to package B?

Hi,

I’m developing with SuiteCRM and I have a question: how can I move a module from package A to package B?
I’ve noticed that every custom module directory has some subdirectories (icons, language, modules, zips) and a manifest.php file, so I don’t think that the simple cut&paste in another package in the file system would be suitable.

Thanks in advance for any answer,

Marco R.
