Always read the release notes to see if there are any issues - that you might need to take note of. It is recommended that you take a - backup of your database and your entire Bugzilla installation before attempting an - upgrade. You can upgrade a 'clean' installation by untarring a new - tarball over the old installation. If you are upgrading from 2.12 or - later, and have cvs installed, you can type <filename>cvs -z3 update</filename>, - and resolve conflicts if there are any. + <para>Upgrading Bugzilla is something we all want to do from time to time, + be it to get new features or pick up the latest security fix. How easy + it is to update depends on a few factors. </para> - - <para>However, things get a bit more complicated if you've made - changes to Bugzilla's code. In this case, you may have to re-make or - reapply those changes. One good method is to take a diff of your customized - version against the original, so you can survey all that you've changed. - Hopefully, templatization will reduce the need for - this in the future.</para> - - <para>From version 2.8 onward, Bugzilla databases can be automatically - carried forward during an upgrade. However, because the developers of - Bugzilla are constantly adding new - tables, columns and fields, you'll probably get SQL errors if you just - update the code and attempt to use Bugzilla.
