The procedure to switch to Git is as follows. The idea is to switch version
control systems without changing the exact version of Bugzilla you are using,
to minimise the risk of conflict or problems. Any major upgrade can then
happen as a separate step. 

Update Bugzilla To The Latest Point Release
===========================================

It is recommended that you switch while using the latest
point release for your major version. You can update to the latest point
release using bzr.

First, you need to find what version of Bugzilla you are using. It should be
in the top right corner of the front page but, if not, open the file
:file:`Bugzilla/Constants.pm` in your Bugzilla directory and search for
:code:`BUGZILLA_VERSION`.

Then, you need to find out what the latest point release for that major
version of Bugzilla is. The
`Bugzilla download page <http://www.bugzilla.org/download/>`_
should tell you that for supported versions. For versions out of support, here
is a list of the final point releases:

* 3.6.13
* 3.4.14
* 3.2.10
* 3.0.11

XXX Do we need below here? Are these versions in bzr? Will anyone be running
them from a bzr install?

* 2.22.7
* 2.20.7
* 2.18.6
* 2.16.11
* 2.14.5

If you are not currently running the latest point release, you should use the
following update command:

|updatecommand|

Where you replace $VERSION by the version number of the latest point release.
Then run checksetup to upgrade your database:

:command:`./checksetup.pl`

You should then test your Bugzilla carefully, or just use it for a day or two,
to make sure it's all still working fine.
