public void doUpgrade()
               throws Exception

We store the actual titles of task lists and the names of the items they contain the body of pages.
We store their complete/incomplete status in the OS_PROPERTYENTRY table.
As such, we do not need to preserve these titles or names in this table. We can use hashes to ensure the keys are under the 200 character limit.
We need only ensure that the way we access this state also uses the hash function. (updated tasklist macro source to do this)
See CONF-3622
