# Restarting Collectors

As announced in the 23.1 release, the Collectors feature and the Connectors in Transformation Hub (CTH) feature have been deprecated, and from the ArcSight Platform 24.2 release on, only existing collectors and CTH deployments are supported. You can continue managing your collectors and CTHs in the platform, but you cannot create any new ones.

To restart one or more Collectors:

1. Click Configuration Management > Bulk Operations.
2. On the Manage Collectors page, select one or more items which you wish to restart.
3. Click Restart.
4. Click Yes to confirm restart. The Collectors are restarted.
