After creation, partitions within our system are permanent and cannot be deleted, nor can their names be reused. This safeguard is in place because partitions may contain log messages exclusive to that partition; deleting it would result in the loss of these logs.

Only active partitions count toward your 50 partition limit. If you've reached this limit, you can decommission unused or unwanted partitions to free up space.

Should you no longer require a partition, you have the option to decommission it. Once decommissioned, the data within the partition remains accessible for search purposes, but the partition itself cannot be reactivated, and its routing expression cannot be altered. 

To decommission a partition:

1. [**New UI**](/docs/get-started/sumo-logic-ui). In the main Sumo Logic menu select **Data Management**, and then under **Logs** select **Partitions**. You can also click the **Go To...** menu at the top of the screen and select **Partitions**. <br/>[**Classic UI**](/docs/get-started/sumo-logic-ui-classic). In the main Sumo Logic menu select **Manage Data > Logs > Partitions**. <br/><img src={useBaseUrl('/img/manage/partitions-data-tiers/partitions-page.png')} alt="Partitions page" style={{border:'1px solid gray'}} width="800"/>
1. To refine the table results, use the **Add a filter** section located above the table. *AND* logic is applied when filtering between different sections, while *OR* logic is applied when filtering within the same section. Click the row for the partition you want to decommission. 
     :::note 
     You can see the suggestions only if there are two or more responses for the same column or section.
