I'm not totally sure, so additional comments are welcome, but afaik all the marks Gnus maintains locally for news are stored as imap flags on the server, like read, seen, ticked and even dormant (might depend on your Gnus version, though). So just switching servers should go alright without further actions in this regard, if the flags are migrated, too. What I'm not sure about is what to do with possibly cached articles. Maybe somebody else can tell more? Regards, Bruno.
