Check and Perform Switch Version Never initiate switch version from the recovery CD. Caution • Perform switch version in the same maintenance window to avoid additional downtime. • The time taken for switch version depends on the size of records in the database. • Always ensure that all the third-party Wallboard server and WFM servers that query the Unified CCX database externally are powered off prior to the switch version process. These servers may cause conflict in database operations. • Update the Unified CCX VM to latest OVA for 100 and 400 Agent profile for the switch version to be successful. This is mandatory as the vRAM required has been changed. For more information, see the Unified CCX Virtualization related information located at: https://www.cisco.com/c/dam/en/us/td/docs/ voice_ip_comm/uc_system/virtualization/virtualization-cisco-unified-contact-center-express.html. • Do not modify the Hostname or IP address of the Unified CCX server before performing switch version.
