Learn important information to consider when upgrading the Vocera Voice Server in a
clustered environment.
Plan for downtime as follows:
- Badge-to-badge calls: Users will experience a short outage (several minutes) while their
badges connect to the upgraded 5.2.0 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 entities may not be synchronized with the standby Vocera 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 Servers during
the entire upgrade process. If you decide to do this, make sure you notify users of the
planned outage.
