Install/upgrade question

I’m not sure if this is the appropriate list to address install
questions, but help would be appreciated. Three things:

  1. fresh install or upgrade? - we’ve had RT running on a machine for
    awhile (I didn’t install it, but it’s very helpful and we’d like to keep
    using it), which we’ve since scrubbed and reinstalled (redhat 7) from
    the ground up. I’ve saved my old rt database and copied it back to the
    machine. The database is getting large (tens of thousands of
    transactions) and I’m wondering if I should just install fresh. If I
    upgrade however, and I want to keep my old database, I probably should
    keep it named “rt” and the MYQL_DATABASE in the Makefile set to:


…is this right? Also, will I get new copies of rt’s bin, etc, lib, and
transactions folders or in order to upgrade properly, do I need to keep
these old folders in /usr/local/rt and make my entry in the Makefile the same:

RT_PATH = /usr/local/rt

…so that it writes over and/or updates the old directories?

  1. RT_MAIL_TAG - I don’t quite understand what I’m supposed to enter
    here… is it totally arbitrary (I know hostname is suggested)? We’ll
    run several different queues, so I don’t know if that makes a difference.

RT_MAIL_TAG = change-this-string-or-perish

  1. WEB_AUTH_COOKIES_ALLOW_NO_PATH - “You’ll never want to enable it,
    unless you’ve got clients with IE4.01sp1…which chokes unless this is
    enabled.” So, does “yes” actually disable AUTH_COOKIES (since it’s
    ALLOW_NO_PATH)?. The language is kind of confusing.
