Upgrade Consideration for a Cluster: Planned Downtime
Learn important information to consider when upgrading the Vocera Voice Server in a
Plan for downtime as follows:
- Badge-to-badge calls: Users will experience a short outage (several minutes) while their
badges connect to the upgraded 5.3.2 server for the first
time and download new firmware.
- Badge-to-phone calls: Users will experience a longer outage while you upgrade the Vocera SIP Telephony Gateway.
- Learned names, learned commands, and pending deletes from upgrades for 4.x Versions: There
is a brief period during the upgrade when learned names, learned commands, and pending
deletions of Vocera Voice Server
entities may not be synchronized with the standby Vocera Voice Server server. To avoid any problems, advise users not to record any learned names or learned
commands and not to delete any entities during the entire upgrade.
Important: If you are concerned about possibly losing some learned names, learned
commands, or pending deletes during the upgrade, you can shut down ALL Vocera Voice Servers during the entire
upgrade process. If you decide to do this, make sure you notify users of the planned outage.
