      Considerations for Upgrade

      • Direct upgrades are supported only from 1.3 and 1.4.
      • Change in configurations and policy for 2FA
        • Two-factor authentication must now be explicitly enabled using the mms.multiFactorAuth.require setting. See [LINK TO DOCS]
      • The default LDAP group separator was changed from , to ;; . See [LINK TO DOCS]
      • Suppressed hosts will only remain suppressed for 30 minutes
        • Previously, if a host was deleted from MMS Monitoring the hostname/port would be added to a suppression list with an infinite lifetime. This was meant to prevent a race condition in which a host in a cluster would be auto-discovered by another member of a cluster before the cluster could fully be removed.
        • Suppressed hosts are now kept on this list for only 30 minutes.
      • mms.remoteIp.header in conf-mms.properties should be set if MMS is behind a load balancer
      • mongo.backupdb.mongoUri is no longer in conf-mms.properties. This was previously a required field in this file. It is still in the backup daemons's conf-daemon.properties.
      • Stored MongoDB profile data is not transferred between OnPrem 1.4 and OnPrem 1.5
        • If the optional feature to collect and store MongoDB profile data in MMS was enabled, this data will not be transferred between OnPrem 1.4 and OnPrem 1.5.


      • When an MMS Backup job fails to bind, the system will periodically and automatically retry
      • All MMS Backup jobs will retry indefinitely
      • Point in Time restores can be selected with one second granularity

      New Features

      • Public API http://mms.mongodb.com/help/reference/api/ currently, need to be visible on help-hosted
      • Explicit support for multiple MMS Backup Blockstore Databases and the ability to pin MMS Groups to specific backup daemons and databases. [LINK TO DOCS]
      • MMS can authenticate using LDAP to both the database backing MMS and the databases being monitored/backed up [LINK TO DOCS]
      • Enhanced auditing [LINK TO DOCS]
      • Ability to acknowledge alerts
      • New cluster page - shows individual, sum or average metrics for all shards in a cluster
