It's not clear whether this is a good idea. We do not restart udevd on
update, so migrating a udev database seems like a bad idea. I also would
have thought that this is no problem, as the old udevd is still running
and uses the old database format (unless udevd re-exec's /sbin/udevd at
some point, which IMO is also a bad idea, it should rather re-exec

As a general rule: A udev update should be followed by a reboot or a
manual udevd restart (both of which would fix your problem).
