I understand this:
- If we want to *link* to a LGPLv3 library, no problem (as even
proprietary code can link to LGPLv3)
- If we want to *copy* LGPLv3 code and statically link it in a
binary made with our "GPLv2 or later" code, we must "upgrade to
But "upgrade to GPLv3" means upgrade the binary to GPLv3, and then we
have to redistribute the source as GPLv3; which is not a problem.
For example I am allowed to redistribute the file apps/metadata.c
"under the terms of the GPL either version 2 or later".
I can choose to redistribute under the version 3 then and change the
license header, then redistribute that file to a third party.
If that third party doesn't like GPLv3 and wants to get the content as
GPLv2, he can choose to download it from the repository which still
says "GPLv2 or later", and choose the GPLv2 terms.

With my understanding our source is already GPLv3 (well it can be that
way every time someone redistributes the source code to someone else).
On the other hand, I have no idea which restrictions apply when we
redistribute a GPLv3 binary.
