See the PCN issued for the Session Manager software release. The Branch Session Manager (BSM) upgrade, in some cases, could involve upgrading Communication Manager Survivable Remote templates as outlined in the document, Upgrading Avaya Aura® Communication Manager. See Product notifications for more information about PCNs and PSNs.
Note:
  • If you are upgrading an active Branch Session Manager, ensure that Branch Session Manager is administered on System Manager and the Enrollment Password is active.
  • Before installing or upgrading the Branch Session Manager, ensure that all the Branch Session Managers are configured in DNS or added to the/etc/hosts file on System Manager.
    An example of the contents of the /etc/hosts file is:
    123.45.6.78       bsm.co.avaya.com bsm
    123.45.6.88      core-asm1.ca.avaya.com core-asm1
    The first entry is the IP address, the second entry is the FQDN, and the third entry is the short hostname (FQDN without the domain name).
  • Ensure that the date and time is in sync between System Manager and System Platform. A clock shift can cause certificate and DRS replication problems.
  • You must upgrade Branch Session Manager to be the same level as the core Session Manager.
