Workstation/Distributor servers is a prerequisite to be present in the system.
Note: Prior to initiating
installation or uninstallation, ensure that only one user session is active on
the target servers. Concurrent user logins are not allowed during this
process.
To install the
Unified CCE 12.6(2) ES101 with maintenance mode (Zero Downtime), follow the
steps:
For more information about graceful shutdown, please refer to Administration guide for unified contact centre enterprise release -https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cust_contact/contact_center/icm_enterprise/icm_enterprise_12_6_2/administration/guide/administration-guide-for-cisco-unified-contact-center-enterprise-release-1262/ucce_m_graceful-shutdown.html?bookSearch=true
