In-Service Migration to 18.5.0
This section describes the steps to perform an in-service software migration of a CPS 14.0.0 to CPS 18.5.0. This migration allows the traffic to continue running while the migration is being performed.
In-service software migrations to CPS 18.5.0 are supported only for Mobile (HA) and GR installations. Other CPS installation types cannot be migrated.
Note |
Graphite data source in Grafana needs to be updated to use configured Graphite/Grafana user credentials before migration starts. If you fail to update the configured user credentials, you gets continuous prompts for Graphite/Grafana credentials as Grafana does not have access to graphite database. All grafana users configured will be available after migration but you need to modify graphite data source in grafana UI with the configured user to access graphite database (to get the graph on grafana). For more information on updating graphite data source, see Configuring Graphite User Credentials in Grafana in CPS Operations Guide. |
