				// Convert dashboards to a new storage format. The old storage format looks
				// like this:

				// {
				// "0": ["PHID-DSHP-A", ...],
				// "1": ["PHID-DSHP-B", ...]
				// }

				// The new storage format looks like this:

				// [
				// {
				// "panelKey": "abcdefgh",
				// "panelPHID": "PHID-DSHP-A",
				// "columnKey": "left"
				// },
				// ...
				// ]

				// One major issue with the old storage format is that when multiple copies of
				// a single dashboard panel appeared on the same dashboard, the UI had a lot
				// of difficulty acting on a particular copy because copies were identified
				// only by PHID and all copies of the same panel have the same panel PHID.
