MMS OnPrem1.5 : Release notes

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.
