# Document Processing Flow in V42

In v42, the Document Processing flow included in the instance is a flow group rather than a single flow. For more information about flow groups, see [Connecting Flows to Other Flows](/v42/docs/connecting-flow-blocks-to-other-flows).

The Document Processing flow group consists of:

- A subflow called “Document Processing Subflow V42,” which contains the latest versions of the blocks in the standard document-processing flow, with the exception of the Input Block and Output Block. This flow is read-only.
- A subflow called “Submission State Notifications.”
- A top-level flow called “Document Processing.” It consists of an Input Block, a block that calls Document Processing Subflow V42, and an Output Block.

  - To learn more about the available settings types and the settings included in each, see [Document Processing Subflow Settings](/v42/docs/document-processing-subflow-settings).

The settings of the type you selected are shown.

1. Edit the settings as needed.
2. Repeat steps 4 and 5 as needed for other types of settings.
3. Click **Save** in the upper-right corner of the page.

## Upgradability

If your business case allows it, we recommend migrating to v42’s Document Processing flow. We designed it so that the effort required to upgrade to future versions of the Document Processing flows would be minimized. When v43 becomes available, you can upgrade to Document Processing Subflow V43 by selecting it in the **Flow Identifier** drop-down list in the Start Document Processing Subflow Block’s settings.

If you use custom flows, we recommend that your flow developers include this capability in those flows, as well.
