Upgrade Path for ERP Feedthrough Running Pre-2.1.0
If you are upgrading an Echo Power Control Processor (EPCP) from a version earlier than v2.1.0, you must first upgrade to v2.1.0. Once you are at v2.1.0, you can proceed to upgrade to the current version. If you do not take this intermediate step, you can lose the existing configuration or fail the update.
As always, we recommend backing up a copy of the configuration to USB before performing any upgrades.
