## Key Features

## Details <a href="#id-2.0.71eventstoreexpandedtablehistoricalbackfill-details" id="id-2.0.71eventstoreexpandedtablehistoricalbackfill-details"></a>

Unizin has completed backfilling all historical event data from an institution’s production event store into the recently developed [expanded events table](/products/data-and-analytics/unizin-data-platform/data-stores/data-lake/udp-event-store/expanded-table.md). This enables institutions to completely migrate their use of event data from the events table to the [expanded events table](/products/data-and-analytics/unizin-data-platform/data-stores/data-lake/udp-event-store/expanded-table.md).

There are many advantages to the expanded table over the events table. Please consider reviewing our [guide to help you make the most of the expanded table](https://gitlab.com/unizin/products-docs-site/-/tree/master/docs/products/data-and-analytics/unizin-data-platform/release-notes/broken-reference/README.md).

{% hint style="danger" %}
**IMPORTANT:** **Unizin intends to retire the events table on August 1, 2021. Please ensure updates are applied to your queries to the new expanded table by this date.**
