Generally yes. Where a package is renamed, typically a transitional dummy package is created with the old name to ease upgrades. Therefore, if you had a package 'foo' installed that has been renamed to 'bar', the name 'foo' in wheezy would be a dummy package which depended on 'bar' to pull it in. > I would assume that when the second group of commands is run any > packages or config files already in the Wheezy box which are later > versions of than those in the Squeeze box would be left alone. Yes.

So long as you have squeeze sources in your apt sources.list in addition to wheezy, or they couldn't be found. > To know what happened when the second group of commands is run can a > log file be thereby created for that purpose? /var/log/dpkg.log is probably what you want. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
