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.
I'm Guessing The install of 0.8.4 (security upgrade) over an 0.8.1 Trac installation is this simple
Can't say for sure, but just untar the download where you had the last one and use the same config script to just install it over what you have already. Don't forget to trac-admin upgrade the database. Don't know if that is needed either, can't hurt.
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
Upgrading sqlite from 2.x to 3.x
The database formats used by sqlite 2.x and sqlite 3.x are incompatible. If you upgrade your sqlite version (this can also happen implicitly if you upgrade pysqlite) then you must convert your database.
To do this, install both sqlite 2.8 and sqlite 3.x (they have different filenames so can coexist in the same directory), then use the following commands (Windows):
c:\...> ren trac.db trac2.db c:\...> sqlite trac2.db .dump | sqlite3 trac.db
(Unix/Linux would be similar but with mv instead of ren)
Then when you're happy with the conversion and tested everything (of course!) you can delete the trac2.db file.
