I've been looking at the issue of installing both drupal6 and drupal7 packages simultaneously during migration (e.g. to migrate one site at a time if there are several sites)
The only obvious issue that sticks out is that both new and old packages suggest the same location for locally installed modules and themes, /usr/local/share/drupal I've opened a bug about this here: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=685333 Given that upgrades are likely to be slow and painful, co-installation of both packages should be as easy as possible -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of "unsubscribe".
