Troubleshoot - Downgrade of Data Collector is not supported
Downgrade of Data Collector is not supported. When the Data Collector downgrade fails, ensure one of the below step is performed:
Uninstall and reinstall the Data Collector to version that is compatible with the NetBackup IT Analytics version on the Data Collector server.
For example: If the Portal version is 11.4.01 and the Collector version is 11.5, uninstall the 11.5 Collector version and install either 11.4.01 or lower version for the collector for upgrade to be successful.
Upgrade the Portal server to the current Data Collector version or higher version.
