Troubleshooting an Upgrade

Use the following tips for help with upgrades:

After upgrading a Data Collector that is registered with DPM, the Data Collector fails to start with the following error about a component ID:
Failed registration for component ID '<unique ID>'
The upgraded Data Collector is using a new component ID stored in the $SDC_DATA/sdc.id file. An upgraded Data Collector that is registered with DPM must use the same component ID as the previous version.
Verify that the $SDC_DATA directory that the upgraded Data Collector is using includes the previous sdc.id file. Then, restart Data Collector.
After upgrading a Data Collector that is registered with DPM, the Data Collector fails to start with the following error about the authentication token:
dpm.appAuthToken cannot be NULL or empty
The upgraded Data Collector is using the new version of the $SDC_CONF/application-token.txt file. The previous version of the file includes the authentication token that this Data Collector instance requires to issue authenticated requests to DPM. As a result, an upgraded Data Collector must use the previous version of the file.
Verify that the $SDC_CONF directory that the upgraded Data Collector is using includes the previous application-token.txt file. Then, restart Data Collector.
