Description: After the upgrade from UFM-SDN Appliance v4.12.0 GA to UFM-SDN Appliance v4.12.1 FUR, the network fast recovery path in opensm.conf is not automatically updated and remains with a null value (fast_recovery_conf_file (null)) |
|
Workaround: If you wish to enable the network fast recovery feature in UFM, make sure to set the appropriate path for the current fast recovery configuration file (/opt/ufm/files/conf/opensm/fast_recovery.conf) in the opensm.conf file located at conf/opensm, before starting UFM. |

Description: Upgrading UFM-SDN Appliance from versions 4.7.0, 4.8.0 and 4.9.0 results in cleanup of UFM-SDN Appliance historical telemetry database (due to schema change). This means that the new telemetry data will be stored based on the new schema. |
|
Workaround: To preserve the historical telemetry database data while upgrading from UFM-SDN appliance version 4.7.0, 4.8.0 and 4.9.0, perform the upgrade in two phases. First, upgrade to UFM-SDN v4.10.0, and then upgrade to the latest UFM version (UFM-SDN appliance 4.11.0 or newer). It is important to note that the upgrade process may take longer depending on the size of the historical telemetry database. |
