The following table identifies the files to download for each supported installation or upgrade scenario.
|Resource Manager||Required files|

Resource Manager provides the ability to reidentify devices. The reidentification process deletes and re-adds the device with a new ID and GUID. When the GUID is changed, the device is removed from that particular Service Impact service. If you reidentify a device, you must manually re-add the device to the service model.
Impact graph update best practice
For best performance, do not manually rebuild an impact graph during a time that overlaps a maintenance window. The graph update and maintenance window operations use the same target graph database. Performing them together might lengthen the time to complete the operations, and might result in transaction rollbacks. For more information about manually rebuilding a graph, refer to the Zenoss Service Impact User Guide.
When you initially upgrade from Service Impact 5.2.3 to 5.3.0, the new version of the product removes accumulated event history that is no longer needed. A temporary performance slowdown might occur while nodes are read.
After Service Impact is installed, Service Impact and Resource Manager are interdependent. However, Resource Manager issues affect Service Impact more frequently than Service Impact issues affect Resource Manager. For this reason, the list of known issues for a given Service Impact release might include items that manifest in Service Impact but are not caused by Service Impact software. Such items are noted in the list of known issues.
In Resource Manager 4.2.4, JMX monitoring of Service Impact is disabled. In Resource Manager 5.x, JMX monitoring of Service Impact is available in Control Center. (ZEN-22353)
