I´m trying to upgrade trac! from 0.10.3 to 0.12. Need help, i basiclally did steps shown here

http://trac.edgewall.org/wiki/TracUpgrade

So i went through this commands without errors:

todasana:~# easy_install —upgrade Trac0.12 Searching for Trac0.12


todasana:~# trac-admin /usr/local/apache2/htdocs/trac_catw3 upgrade


todasana:~# trac-admin /usr/local/apache2/htdocs/trac_catw3 wiki upgrade


todasana:~# trac-admin /usr/local/apache2/htdocs/trac_catw3 repository resync ‘*’


Didn´t do Step 5 Refresh static resources, because i did not understand it, and i think it does not apply to me: trac-admin /path/to/env deploy /deploy/path

then i
restarted apache:
/etc/init.d/apache2 restart

got this error in the browser now:
Mod_python error: “PythonHandler trac.web.modpython_frontend”
Traceback (most recent call last):
File “/usr/lib/python2.4/site-packages/mod_python/apache.py”, line 299, in HandlerDispatch

if participant.environment_needs_upgrade(db):
File “/var/lib/python-support/python2.4/trac/env.py”, line 373, in environment_needs_upgrade
raise TracError, ‘Database newer than Trac version’

TracError: Database newer than Trac version

got Python 2.4.4 (#2, Jan 24 2010, 11:19:18)
mysql: Server version: 5.0.32-Debian_7etch11-log Debian etch distribution

IT OCCOURS TO ME THAT SOMETHING SHOULD BE DONE WITH THE DATABASE OR CONFIG FILES, BUT NOT SURE WHAT BECAUSE THERE IS NOTHING IN THE DOCS ABOUT IT!
Guys have a great day!!

    It sounds like the version of Trac being run by Apache is the older version and not the version you just installed. Verify that the version of Trac you are running is the version you think you are running.
