## Summary of Grandfathered and exempted tables

These distinctions are important for understanding how table entitlements affect your subscription and license usage.
Please refer to your organization's ServiceNow contract for specific details related to your entitlements and legal terms.

## Grandfathered Tables

Grandfathered tables represent legacy custom table entitlements preserved through a one-time license migration process. This ensures that existing custom tables on your production instance do not count against new custom table entitlements.

* They cannot be transferred, reused, or reclassified as another custom table type.
* If a grandfathered table is deleted, it cannot be replaced by classifying another table as grandfathered.
* Grandfathered tables remain visible in the Custom Table Inventory even after deletion.
* Grandfathered tables must be mapped to a grandfathered table subscription, especially when mixed with other custom tables under different subscriptions.
* Admin assistance from Customer Service and Support is available to help with mapping grandfathered tables to the correct subscriptions.

**Example scenario:** If your organization has a grandfathered subscription for 25 tables and purchases additional subscriptions totaling 55 custom tables, the total entitlement becomes 80 custom tables. Once a table is assigned to the grandfathered subscription, this assignment is permanent.

## Exempted Tables

Exempted tables are custom tables that do not count against your subscription entitlements. They generally include custom extensions of system-related tables (e.g., `sysportalpage`, `sysuserpreference`) used for operational improvements.

* You can view exempted tables by searching `uaexemptedtableinventory.list` in the filter navigator.
* The **Custom Table Guide legal schedule** defines which tables qualify as exempted, and these legal terms are enforced based on the contract execution date.

## Practical Implications for ServiceNow Customers

* Understanding grandfathered tables helps you preserve legacy entitlements and avoid unexpected impacts on your custom table counts.
* Proper mapping of grandfathered tables to subscriptions ensures accurate entitlement management and compliance.
* Recognizing exempted tables allows you to extend key system tables without affecting your subscription limits.
* Use the provided filter navigator commands to identify grandfathered and exempted tables in your instance.
* Contact Customer Service and Support for assistance with subscription mappings and clarifications.  
Grandfathered and exempted custom tables are treated differently than other custom tables on your instance. Refer to your organization's ServiceNow® contract for additional information.

## Grandfathered tables {#grandfathered-and-exempt-tables-v2__section_hhx_zt1_3nb}

Depending on your organization's legacy subscription entitlements and contractual migration, grandfathered tables might be allotted to your production instance. Grandfathered table entitlements enable preservation of your
organization's previous custom table entitlements through license migration. This one-time process ensures that custom tables that currently exist in a production instance don't count against your new custom table
entitlements.

Grandfathered custom tables can't be transferred, reused, or otherwise classified as another custom table type. If you delete a grandfathered custom table, you can't classify any other custom table as a grandfathered custom
table to take its place. Once a custom table has been associated with a grandfathered table subscription, it remains in the Custom Table Inventory even if the table is deleted from the instance.

To view your grandfathered tables, enter <kbd class="ph userinput">ua_custom_table_inventory.list</kbd> in the filter navigator, and then add a filter with the condition \[Allotment type\] \[is\] \[Grandfather\].

If you have a combination of custom and grandfathered tables in one application, the grandfathered tables must be mapped to a grandfathered table subscription. The remaining custom tables to one other subscription.
Reach out to Customer Service and Support for help mapping a grandfathered table to a grandfather table subscription.  

## Grandfathered tables on an instance {#grandfathered-and-exempt-tables-v2__example_prf_ky1_3nb}

Scenario: Your organization purchases three new subscriptions with entitlements for a total of 55 App Engine Starter custom tables (formerly Bundled Custom Tables). To ensure your organization doesn't lose the previous custom
table entitlements, a grandfather subscription with an entitlement for 25 grandfathered tables is allotted to your instance. This subscription requires the admin to identify and map the existing 25 tables. These subscriptions
result in a total custom table entitlement of 80. Once a custom table has been assigned to the grandfather subscription there is no option to revert this.

## Exempted tables {#grandfathered-and-exempt-tables-v2__section_jfz_ky1_3nb}

Exempted tables are custom tables that don't count toward your subscription entitlements. These tables consist mostly of custom extensions of certain system-related tables, such as sys_portal_page and sys_user_preference, that
you extend for operational improvements in your production instance.

To view a list of exempted tables, enter <kbd class="ph userinput">ua_exempted_table_inventory.list</kbd> in the filter navigator.  
The [Custom Table Guide legal schedule](https://www.servicenow.com/content/dam/servicenow-assets/public/en-us/doc-type/legal/custom-table-guide.pdf) provides the complete definition of which tables are considered exempt.  
Note:  
Legal schedules are enforced based on when the contract is executed.
