  - 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.
  - Upgrading and Migrating to New Hardware
    If you are deploying new hardware in conjunction with your upgrade, please complete the upgrade in the following general steps.
  - Upgrades and the web.config file
    If you have customized your configuration by modifying the web.config file, running the Upgrader does not affect your customization.

Troubleshooting during Upgrading

If you encounter issues during the execution of the Discover Upgrader, review the steps documented here.

Note: Do not attempt to rerun the Upgrader. Rerunning the Upgrader corrupts the system.

Note: Do not attempt to manually manipulate data files to resolve upgrade issues.

Event migration failure

Note: If event definitions do not successfully migrate during upgrading of the Report Server, Processing Servers cannot be restarted, and they continue to spool data. To prevent filling the spool space on disk and dropping of hits, this issue should be addressed as soon as possible.
