Enterprise Testing Services Notification
Application Lifecycle Management (ALM) is upgrading the Quality Center (QC) tool from Version 12 to Version 17. The upgrade and cutover process will begin in April 2025, with fully automated, application-by-application data migration with no impacts to existing data on the legacy server. A Product Owner (PO) from the Enterprise Testing Services (ETS) team will reach out to Application Development Organizations (ADOs) to discuss individualized scheduling.
No action is needed at this time. If your ADO is affected by this migration, you will be contacted by the ETS team PO beginning in April to review your schedule and plan your individual migration. If you have questions about the ALM upgrade, please contact your assigned Hosting Coordinator.
