    This command takes an existing buildmaster working directory and

    buildbot. When this command is finished, the buildmaster directory should
    look much like a brand-new one created by the 'create-master' command.

    Use this after you've upgraded your buildbot installation and before you
    restart the buildmaster to use the new version.

    If you have modified the files in your working directory, this command
    will leave them untouched, but will put the new recommended contents in a
    .new file (for example, if index.html has been modified, this command
    will create index.html.new). You can then look at the new version and
    decide how to merge its contents into your modified file.

    When upgrading from a pre-0.8.0 release (which did not use a database),
    this command will create the given database and migrate data from the old
    pickle files into it, then move the pickle files out of the way (e.g. to
    changes.pck.old).

    When upgrading the database, this command uses the database specified in
    the master configuration file.  If you wish to use a database other than
    the default (sqlite), be sure to set that parameter before upgrading.

    This command creates a buildmaster working directory and buildbot.tac file.
    The master will live in <dir> and create various files there.  If
    --relocatable is given, then the resulting buildbot.tac file will be
    written such that its containing directory is assumed to be the basedir.
    This is generally a good idea.

    At runtime, the master will read a configuration file (named
    'master.cfg' by default) in its basedir. This file should contain python
    code which eventually defines a dictionary named 'BuildmasterConfig'.
    The elements of this dictionary are used to configure the Buildmaster.
    See doc/config.xhtml for details about what can be controlled through
    this interface.

    The --db string is evaluated to build the DB object, which specifies
    which database the buildmaster should use to hold scheduler state and
    status information. The default (which creates an SQLite database in
    BASEDIR/state.sqlite) is equivalent to:

      --db='sqlite:///state.sqlite'

    To use a remote MySQL database instead, use something like:

      --db='mysql://bbuser:bbpasswd@dbhost/bbdb'
    The --db string is stored verbatim in the buildbot.tac file, and
    evaluated at 'buildbot start' time to pass a DBConnector instance into
    the newly-created BuildMaster object.
