[docs]def upgrade(migrate_engine):
    # A migration here is not needed because the actual marshalling of data
    # from the old column to the new column is done in the contract phase. This
    # is because using triggers to convert datetime objects to integers is
    # complex and error-prone. Instead, we'll migrate the data once all
    # keystone nodes are on the Pike code-base. From an operator perspective,
    # this shouldn't affect operability of a rolling upgrade since all nodes
    # must be running Pike before the contract takes place.
