UPGRADING FROM PREVIOUS VERSIONS

    For the most part, upgrading Mailman is as easy as just installing
    the latest version over the existing version.  However, there are
    some changes that need to be taken care of manually.

    What you need to do depends on the version you are using and the
    version you are upgrading to.  In all cases, you should first turn
    off your mail and web access to your Mailman installation.  You're
    essentially upgrading a database, and it's usually a good idea to
    make sure the database cannot be modified in the middle of the
    upgrade.

    My recommendations are

    - Turn off your incoming mail daemon.  Most remote smtp servers
      will simply queue up messages destined for your domain if port
      25 is shut off.

    - Temporarily disable web access to Mailman.  You can do this by
      either turning off your web server temporarily, or by setting up
      a temporary redirect to a "service unavailable" page for the
      Mailman URLs.  Refer to your web server documentation for
      details.

    Mailman will NOT upgrade the template files for existing lists.
    Chuq Von Rospach gives some useful advice in this message to the
    users mailing list:

UPGRADING FROM 2.0.1 to 2.0.2

    Nothing much more than running "make install" (after upgrading)
    should be necessary.

UPGRADING FROM 2.0 to 2.0.1

    Nothing much more than running "make install" (after upgrading)
    should be necessary.

UPGRADING FROM 2.0 beta to 2.0 final

    You MUST re-run configure; running config.status is not sufficient
    due to some recent changes in the autoconf scripts.  You can do a
    head of config.status if you don't remember the options you
    originally ran configure with.

    The cron jobs for Mailman 2.0 final have changed considerably,
    including the frequency with which they run.  You should reload
    cron/crontab.in for the `mailman' user to get the right settings.
    See the INSTALL file for details.

    FAILURE TO DO THIS WILL RESULT IN A LESS THAN OPTIMALLY FUNCTIONAL
    MAILMAN INSTALLATION.

UPGRADING FROM 1.x to 2.x

    In addition to the instructions above, I highly recommend that you
    make sure your Mailman queue is cleared /before/ upgrading.

    Mailman version 1.x had a cron script called run_queue which was
    part of it's bulk mailer.  With Mailman 2.x there is no default
    bulk mailer (it lets the MTA handle this), and it is currently
    unknown what the effects of upgrading are on the run_queue script,
    but I'll bet it's not good. :)

    The way to make sure that your Mailman queue is empty is to look
    in your $prefix/data directory.  If you see any files that start
    with "mm_q." you've still got messages waiting on the queue.  You
    can run $prefix/cron/run_queue by hand until the queue is cleared.
    Multiple invocations of this script won't help though; they lock
    each other out.  Also, be warned that clearing the queue can take
    a while and may cause a large load on your system (two reasons why
    all this stuff has been redesigned in 2.x :).

    You do not need to run "make update" if you are upgrading from
    version 1.0 or 1.1 to version 2.0, since this is now run
    automatically when you do a "make install".  However you should
    modify your crontab entries to execute cron/qrunner instead of
    cron/run_queue.  You can also safely remove the file
    $prefix/cron/run_queue.

    If you are upgrading from a pre-1.0 beta, you need to follow the
    instructions below.

UPGRADING FROM PRE-1.0 to 2.x

    You need to do a few extra things to make sure that the file
    system layout for the early 1.0 betas is upgraded to the 1.x
    configuration.  There are two ways to do this.

    First, from the source directory, after you've done a "make
    install" you can run "make update".  "make update" creates a file
    named "update.log" in the top level of the source distribution.
    If the script that updates the Mailman filesystem encounters
    something that is not resolvable, it will log info about this to
    "update.log".  This is worth checking after the upgrade completes.

    You can also just change to the installation directory (i.e. $prefix)
    and run bin/update.  This is the same as above except that the
    update.log file is not generated.

    Check your crontab entry.  Remove any runs of obsolete scripts, in
    particular cron/upvolumes_yearly, cron/upvolumes_monthly, or
    cron/archive.

WHAT "MAKE UPDATE" DOES

    Below is an annotated listing of the things that "make update"
    does.  Hopefully, this will help resolve any problems you are
    having.

    Note that it can't hurt to run "make update" each time you
    upgrade, but if you're running version 1.0 or newer, it won't help
    much either!

    - To upgrade to 1.0b10, you will need to copy
      templates/options.html to lists/<listname>/options.html for each
      mailing list you have.  However, if you have edited the
      options.html file, say from the Web interface, you will have to
      merge these changes in manually.

    - The upgrade to 1.0b7 included the removal of
      Mailman/smtplib.py{,c} since Mailman now uses the default Python
      1.5.2 version of smtplib.  [NOTE HOWEVER THAT MAILMAN 2.0 ADDS
      THIS FILE BACK IN Mailman/pythonlib].

    - Archiving files are moved around as part of integrating
      Pipermail into Mailman, as of 1.0b6.  In particular,

      1) if a list has only a private mbox archive
      $prefix/archives/private/<listname> is moved to 
      $prefix/archives/private/<listname>.mbox/<listname> 

      2) if a list has only a public mbox archive
      $prefix/archives/public/<listname> is moved to
      $prefix/archives/private/<listname>.mbox/<listname>

      and a symlink is made that points
      $prefix/archives/public/<listname>.mbox to
      $prefix/archives/private/<listname>.mbox/<listname>

      3) if a list has both private and public mbox archives, 
      make update picks one of the above 2 configurations based on
      whether or not the list currently is archived publicly.  It then
      renames the other mbox to mbox.preb6.

      4) if a list used recent CVS sources, where archives were placed in
      $prefix/public_html/archives, then these are moved to
      $prefix/archives/private/<listname> and a symlink is made from
      $prefix/archives/public/<listname> to that spot if the list's
      archives are public.  Also, a permissions-related security
      problem is removed.

      To integrate mbox archives of old lists, log in as user `mailman'
      and run $prefix/bin/arch <listname> <path-to-mbox-archive>.

      Also, by default, beta6 does both mbox and html based archiving,
      but you can configure Mailman to do one, both, or neither.
      Please see $prefix/Mailman/Defaults.py for details.

      There was a short period of time when the CVS sources archiving
      code was not organized into its own package.  The pickled
      articles in the archives that were placed into archives during
      this period stored the path to the module HyperArch, but that
      module has moved.  You can quick fix this by running

      ln -s $prefix/Mailman/Archiver/HyperArch.py \
              $prefix/Mailman/HyperArch.py  

    - If upgrading from version 1.0b4 or earlier, "make update" moves
      list-specific templates.  For each list,
      $prefix/templates/<listname>/* is moved to $prefix/lists/<listname>.
      Please reference the generic templates in $prefix/templates to see
      if any variables have changed (There shouldn't be many, only
      options.html was updated from b5 to b6).

      For really old versions of Mailman, you may not even have
      <listname> subdirectories in $prefix/templates!  In this case
      you will need to manually copy some files into your new list
      directories.  Here's an example shell command that will do the
      trick:

      cp templates/{archives,handle_opts,listinfo,roster,subscribe}.html lists/<listname>

    - Some modules that existed in previous versions, but that have
      been replaced with newer (differently named) modules, are
      removed.
