You should consider the following changes when migrating to 1.16:

DB Updates
----------

This release has schema changes to support tracking history for hosts.

    * new table: ``host_config``
    * some fields from the ``host`` table have moved to ``host_config``
    * the ``host_channels`` table now has versioning data like the other
      versioned tables

As in previous releases, we provide a migration script that updates the
database.

Other changes
-------------

There are numerous other changes in 1.16 that should not have a direct impact
on migration. For details see:
