That is ok. I should have added that that version A contains GPL V2
only code that is from elsewhere.
Suppose a package XX has a version-A under GPL-V2
and a forthcoming
version-B. Suppose also that version -B is a severe modification of
version-A. Now if version-B is to be released under GPL-V3 and suppose
the earlier version is also to be maintained for some time, then I
believe that the code from version-A would not be usable in version-B.
Or how is this migration handled ?
Only those who owns the copyright to the package XX can change the
package version from GPL v2 to GPL v3. The same people (or those who
submit patches to v2 only branch) can relicense the code from v2 only
branch to v3.
I don't think it is a big issue, if you can make a v2 to v3 transition
from A to B, then why not the patches?
It seems that is a problem. Back porting
anything from B to A would
be providing for treacherous computing possibly. So in this kind of
situation it makes sense to stop maintaining version A. If a patch is
considered for version A and that is relevant for version B, then it
should be released for version B alone.
