# About the AUP Upgrade Process

Note: The process discussed in this section only applies to upgrading connectors and to upgrading a remotely-managed Connector Appliance. If you are upgrading the local ArcMC (localhost), use an ENC file instead.

To upgrade a connector or to upgrade a remotely-managed Connector Appliance, you need to:

- Upload the appropriate `.aup` upgrade file to the Upgrade Files repository, as described below.

- Apply the `.aup` upgrade file from the Upgrade Files repository to the container (see Upgrading All Connectors in a Container).
