DAS Enterprise Edition (formerly Professional Edition) includes the SQL Explorer and Audit feature. The feature's capabilities, data storage model, and billing rules differ across Enterprise Edition versions. This page explains those differences and covers common questions about migrating between versions.
Version comparison
On the Version Management page of the DAS console, the tab under which a database instance is listed identifies its Enterprise Edition version.
The following table compares SQL Explorer and Audit across all Enterprise Edition versions.
| Item | DAS Enterprise Edition V3 | DAS Enterprise Edition V2 | DAS Enterprise Edition V1 | DAS Enterprise Edition V0 |
|---|---|---|---|---|
| Billable items | Pay-as-you-go. Billed separately for: log traffic, log index, SQL Explorer, hot storage, cold storage, cold query, and download. V3 uses hybrid storage for hot and cold data and offers granular, feature-level billing—reducing costs compared to earlier versions. See Billing details. | Pay-as-you-go. Billed for: hot storage, cold storage, and cold query. V2 uses a different underlying storage architecture from V1, with a hybrid storage model for improved performance at lower cost. See Billing details. | Billed as a subscription fee plus a pay-as-you-go storage fee for SQL Explorer and Audit. All data is stored in hot storage. See Billing details. | Pay-as-you-go. Charged for SQL Explorer and Audit data storage. All data is stored in hot storage. See Billing details. |

Limitations during migration
While DAS Enterprise Edition data is being migrated, you can only use SQL Explorer and Audit for the source version. Billing follows the source version's rules during this period.
After the migration completes, DAS automatically disables SQL Explorer and Audit for the source version and enables it for the destination version. Billing then switches to the destination version's rules. For more information, see Billing details.
