Traditionally, it is not possible to do an in-place upgrade of the CC service, due to the abundance of (statistical) data and the changes in functionality and missing backwards compatibility. It is however possible to migrate a CC80 instance to a CC90 instance and transfer the administration data. As in previous versions:
– Reporting/stat definitions are not transferred
– Reporting/stat data is not transferred
This data is however not lost. When moving from CC80 to CC90, you can turn off the CC service and reuse the license for CC90, and the reports and reporting data will remain available to Web Center users, as well as the scheduled reports. This does not require a CC service to be running.
PLEASE READ THE MIGRATION SCRIPT CAREFULLY BEFORE EXECUTING ! THE DOCUMENT CONTAINS MORE CRITICAL INFORMATION FOR THIS MIGRATION AND MIGRATION FAILLURE COULD LEAD TO CORRUPT DATA.
The migration script and documentation are provided in the downloads section of this website
