When planning an upgrade of Service Management products, administrators may wonder if there is a specific order that servers must be upgraded?
Some examples of types of servers
Service Desk Manager BG (AA)
Service Desk Manager Standby (AA)
Service Desk Primary (Conventional)
Service Desk Secondary (Conventional)
xFlow
REST
Service Catalog
Release : 17.x
Component : SDM - Install/Upgrade/Configuration
There is no specific order necessary for upgrading Service Management
In AA environments it is suggested to upgrade the Background Server first, next the Standby Server, and finally the Application Servers
Otherwise it is suggested to upgrade Service Desk Manager servers first.
Keep in mind, these are suggestions and not hard rules.
