Bug: 2688
This bug deals with migrating data when upgrade happens. This fix
initially takes care of 1.3-1.4 data upgrade required. It moves the contents
of the old index table in 1.3 to the new index table in 1.4
Run over each row-key in the index table.Lookup for the flow info in the
FlowRecord table and insert the information in the new table. After
update truncate the old tables.
The db-utils take oldversion as its argument and runs through a chain of
upgrade functions to move the data.
