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.
