# Automatic synchronization of published TRM catalogs

# Automatic synchronization of published TRM catalogs {#ariaid-title1}

Release version: Brazil  
Updated September 10, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
After you publish a TRM catalog, most updates to TRM data are synchronized automatically with the published knowledge base content.

## What updates automatically {#automatic-synch-published-catalogs__section_ixt_qt4_l3c}

The following changes are reflected in the published knowledge base articles without requiring you to republish the catalog:

* Updates to TRM product fields that are included in the publishing configuration
* Updates to TRM product lifecycle fields that are included in the publishing configuration
* Date-driven lifecycle phase transitions, where the TRM phase changes based on configured start and end dates

{#automatic-synch-published-catalogs__ul_dr4_st4_l3c}Automatic synchronization ensures that published TRM catalogs remain up to date as underlying TRM data changes.

## When republishing is required {#automatic-synch-published-catalogs__section_pst_wt4_l3c}

You must republish the TRM catalog to apply certain structural or global changes to the published knowledge base content.  
Republishing is required in the following scenarios:

* Renaming a TRM phase (for example, changing Divest to Divesting)
* Making structural changes that affect how content is rendered across all articles, such as modifying TRM category names or TRM phase definitions
{#automatic-synch-published-catalogs__ul_hsl_yt4_l3c}

When republishing is required, the Publishing Center prompts you to republish the catalog so that the changes are applied consistently across all published articles. For instructions on republishing, see [Republish a TRM catalog after updates](https://www.servicenow.com/docs/Szu~CrfdJha6jI6~9nTyuQ "Republish a TRM catalog to apply the latest TRM updates to the published knowledge base content.").
