Enterprise to Community downgrade

We are currently using Enterprise mongodb replica set and want to downgrade to Community version. Are there any steps documented to perform the downgrade with no downtime on existing enterprise instance? Any precautions we need to take before performing the downgrade?

If you are not using any Enterprise version options, you can switch to exact same version of Community as they are binary compatible. Just follow these directions but in reverse: https://docs.mongodb.com/manual/administration/upgrade-community-to-enterprise/
