I can confirm this works well. I have a production database which
was moved from 6.2 to 7.0 and works just fine (it was installed for
testing on a machine with 6.2, then a new server was purchased and I
put 7.0 on it (plus patches)). Being lazy, I remembered it's only
about the linking, so I simply copied it over with rsync. Works like
a charm.
