Read the + `Release Notes <http://www.bugzilla.org/releases/>`_ of the version you're + upgrading to and all intermediate versions, particularly the "Notes for + Upgraders" sections, if present. They may make you aware of additional + considerations. + +#. Run the :ref:`sanity-check` on your installation. Attempt to fix all + warnings that the page produces before you start, or it's + possible that you may experience problems during your upgrade. + +#. Work out how to :ref:`back up <backups>` your Bugzilla entirely, and + how to restore from a backup if need be. + +Customized Bugzilla? +-------------------- + +If you have modified the code or templates of your Bugzilla, +then upgrading requires a bit more thought and effort than the simple process +below. See :ref:`template-method` for a discussion of the various methods of +code customization that may have been used. + +The larger the jump you are trying to make, the more difficult it +is going to be to upgrade if you have made local code customizations. +Upgrading from 4.2 to 4.2.1 should be fairly painless even if +you are heavily customized, but going from 2.18 to 4.2 is going +to mean a fair bit of work re-writing your local changes to use +the new files, logic, templates, etc. If you have done no local +changes at all, however, then upgrading should be approximately +the same amount of work regardless of how long it has been since +your version was released. + +If you have made customizations, you should do the upgrade on a test system +with the same configuration and make sure all your customizations still work. +If not, port and test them so you have them ready to reapply once you do +the upgrade for real. |
