To ensure uninterrupted service and data protection, we strongly recommend that all customers review the provided Knowledge Base (KB) article and follow the migration instructions. This impacts all regions and all CCS customers. Recommended Action: All recipients of this Field Notice are advised to review the KB article from the additional Resources section for detailed information and recommended preventive actions.
