  - Overview of the Upgrade Process
    The objective of the upgrade is to minimize downtime and data loss. The recommended approach is to suspend the processing components, letting data spool to disk while the Data Collector collects any unaggregated statistical data. The system can then be upgraded. When it is restarted, it will attempt to work off the spooled data until it catches up.
