UPGRADING FROM 0.01

The upgrade process is very similar to installation:

perl Makefile.PL

make

make install

Once make install finishes, the database upgrade can be performed:

/opt/rt5/sbin/rt-setup-database --action insert --datafile etc/upgrade/0.02/content \
    --package RT::Extension::ChangeManagement --ext-version 0.02

Finally, clear your mason cache:

rm -rf /opt/rt5/var/mason_data/obj

and restart your webserver.
