<this is a crude guide to upgrade, needs to be expanded/redone>

...make a database dump

cd /var/www cp -R HaCi HaCi-backup tar zxvf HaCi_0.961.tar.gz ...check ownership of files (logs must be www-data or whatever your apache runs as) diff -ubr HaCi-backup HaCi ...edit back the changes you had done (typically: add back your CSS layout definition to internal.conf) restart apache (remember mod_perl is cached!)

done!
