MongoDB Documentation, Release 3.0.4 Upgrade Binaries Before upgrading the authentication model, you should first upgrade MongoDB binaries to 3.0. For sharded clusters, ensure that all cluster components are 3.0. Upgrade Drivers You must upgrade all drivers used by applications that will connect to upgraded database instances to version that support SCRAM-SHA-1 . The minimum driver versions that support SCRAM-SHA-1 are: See the MongoDB Drivers Page 278 for links to download upgraded drivers. Requirements To upgrade the authentication model, you must have a user in the admin database with the role userAdminAnyDatabase (page 412). Timing Because downgrades are more difficult after you upgrade the user authentication model, once you upgrade the MongoDB binaries to version 3.0, allow your MongoDB deployment to run for a day or two before following this procedure. This allows 3.0 some time to “burn in” and decreases the likelihood of downgrades occurring after the user privilege model upgrade. The user authentication and access control will continue to work as it did in 2.6. If you decide to upgrade the user authentication model immediately instead of waiting the recommended “burn in” period, then for sharded clusters, you must wait at least 10 seconds after upgrading the sharded clusters to run the authentication upgrade command. 819 12.1.
