Hey Andreas,

I am not sure your proposed solution will work as both versions are already
used (by different users).

So the problem is not about upgrading an old installation from H4 to H5 but
to move/copy some users (the adressbooks of some users) between running H4
and H5 instances. 

Greetings,
Andreas
