### Updating Instance

The permitted ***Time to Live*** limit for a Data Store is only 30 days (maximum). If it goes above that, data will not be there in the Story. Hence, the user can manually update the instance. The ***Days Left*** column will highlight such condition as flashing ***Expire*** status in the red color. Click the user gets redirected to update the instance for the selected Data Store so the data will be refreshed again in the ***ES*** or ***MongoDB***.

* Navigate to the ***Create New Story*** page.
* Select a Data Store from the ***Personalised*** category that has been expired.
* Click on the Data Store.
* The ***Time to Live*** (TTL) option appears.
* Mention no. of days (up to 30 days is allowed for TTL)
* Click the ***Refresh*** option.

* The Data Store gets refreshed, and the inserted no. of days get reflected under the Days Left column.

{% hint style="info" %}
Please Note: The user can distinguish between Datastores:

* Distinguish between instances and scheduler-based data stores.
* Distinguish between the ***Active*** and ***Expired*** instances.

  * The Expired Data Stores are mentioned with the Expired Status.
