# This script completely migrates a <= 0.8.x Trac environment to use the new
# default ticket model introduced in Trac 0.9.
# In particular, this means that the severity field is removed (or rather
# disabled by removing all possible values), and the priority values are
# changed to the more meaningful new defaults.
# Make sure to make a backup of the Trac environment before running this!
