To ensure that you are using the latest Compass features and improvements, it is recommended to use the latest version of MongoDB Compass. To upgrade Compass, you can either manually install the latest version or enable automatic updates. You can download and install the latest version of Compass from the MongoDB Downloads page at any time. Check the Software Requirements for your operating system and desired version of Compass to ensure Compass is compatible with your system. You do not need to uninstall previous versions of Compass to upgrade. NoteIf you are running macOS Catalina or later, you may have to modify your system settings to grant Compass permission to run. For more information, see . You can enable automatic updates to the latest version of Compass on the Help > Privacy Settings dialog. MongoDB Compass does not install any updates without your explicit permission. Instead, Compass prompts you to upgrade when a new version is available. On macOS systems, the first time that you update MongoDB Compass to version 1.20 or later, you will need to allow access to your system storage for each saved connection in Recents and Favorites. When prompted for your keychain password, click Always Allow to prevent being prompted for your password in the future. This ensures MongoDB Compass has access to your saved connections when updating to new versions. To migrate from Compass Community edition to the fully-featured edition of Compass and retain any saved data such as saved connection strings and favorite queries, you must migrate that data to your new edition of MongoDB Compass. MongoDB Compass stores saved connections, queries, and aggregation pipelines in folders in your file system. You can copy these folders to the corresponding folder for your upgraded Compass version to avoid recreating your saved data.
