Upgrading fine tuned custom extractor processors is now available in Preview.

The feature allows you to fine tune a new processor version with a newer base version, while keeping the configurations of the previously fine-tuned processor version selected. This is available through the UI in the Deploy & use tab in the console.

This is currently supported for upgrading pretrained-foundation-model-v1.4-2025-02-05 to pretrained-foundation-model-v1.5-2025-05-05.
