Upgrade Instructions

Trac environments sometimes need to be upgraded before they can be used in a new version of Trac. This document describes the steps necessary to upgrade an environment.

From 0.7.x to 0.8

The database schema was changed between 0.7.x and 0.8. Existing environments must be upgraded before they can be used with Trac 0.8.

The following command will automatically perform the upgrade:

 $ trac-admin /path/to/projectenv upgrade

Trac environments are created with a default set of wiki pages. It's recommended to update these pages on existing environments whenever Trac is upgraded to get up-to-date documentation and additional functionality. The following command will perform the update:

 $ trac-admin /path/to/projectenv wiki upgrade

0.8 adds a new roadmap feature which requires additional permissions. While a fresh installation will by default grant ROADMAP_VIEW and MILESTONE_VIEW permissions to anonymous, these permissions have to be granted manually when upgrading:

 $ trac-admin /path/to/projectenv permission add anonymous MILESTONE_VIEW
 $ trac-admin /path/to/projectenv permission add anonymous ROADMAP_VIEW
