Updating from LGPL 2 to LGPL 3

[Francesco Fumanti]

Hi,

I am looking at preparing a new release of the python-virtkey package and wanted to use that opportunity to update its license from LGPL 2 to LGPL 3.

However, some files of the package did not change since the last release of the package. Thus I wonder whether I can only update the files that have changed to LGPL 3.

Does anybody know whether it is allowed to also update the files that did not change from LGPL 2 to LGPL 3.

Thanks in advance for any advice,

Francesco.
