Using external instances enable better performance and scalability. Follow the steps on this page to set up external MongoDB and Redis for Appsmith.
To use external MongoDB with Appsmith v1.9.0 onwards, you need MongoDB version 5 or higher. Follow the steps in the MongoDB official documentation to Upgrade a Replica Set to 5.0
