[oXygen-user] How to transfer Oxygen from an old computer to a new one?

Dear list members, I have just discovered the existence of this list this morning and it is just possible that the question I am having has been asked one hundred times, in which case I apologize in advance. What is the correct procedure for transferring Oxygen from one computer to another one. Do I have to uninstall from the old computer and reinstall on the new? (as is the case for instance for Adobe Creative Suite). What happens if the old computer has become so unstable that it is difficult to access? I am having all the Oxygen licence numbers safely stored on some external hard disk. Thanks for any pointer. -- Jean-Luc Chevillard (CNRS, Paris)
