Remove Execution Engine

In our development environment, we have the process-analytics and process-execution engines running on one server, and the remaining engines running on another server (distributed mode).

We would like to reconfigure this installation to have just one server running everything.

Unfortunately, the server we want to remove is the server that runs the process-analytics and process-execution engines.

Appian documentation says the following:
"Appian does NOT support the removal of execution engines."

My plan was to add the process-analytics and process-execution engines to the server we want to keep, start everything up so data replicates, take it all down again, and remove the engines from the second server.

Would this be considered "removal of execution engines"?

Or does that statement just mean we cannot completely remove an engine from all servers?

Any advice would be appreciated.

Thank you.
