Installing MongoDB V3.2.12 on your remote system

Edit online

If your V8.1.3 Cloud APM server is connected to a remote MongoDB, you must install MongoDB V3.2.12 before you upgrade the Cloud APM server.

You can uninstall MongoDB V3.x and reinstall V3.2.12 on the remote system, but this procedure requires you to stop the Cloud APM server. Alternatively, to avoid stopping the Cloud APM server, you can install MongoDB V3.2.12 on another remote system and update the backup file that is used to upgrade the Cloud APM server to include the MongoDB V3.2.12 connection parameters.
