When the Cloud GL cube name changes, how can the source GL be switched to the new GL cube for integr

We setup integration to extract data from Cloud GL COA_3 cube in FCCS Data management. We migrate FCCS environment to a new environment, and extract data from a new Cloud GL environment COA_2 cube, so the source cube name changes from COA_3 to COA_2. How should I proceed to make the integration extract data from COA_2? I know I can create a new integration to extract data from Cloud GL COA_2 cube, but I want to know how to do it without creating a new interface.

Please refer to attached screenshot. We want to keep this DM rule based on this import format, but update the Source to pull data from a different ERP cube.
