What are the steps required to perform an active MUF upgrade from Datacom/DB 14.0 or from 15.0? Or from 15.0 to 15.1?
The upgrade procedures were enhanced with Datacom//DB Version 15.0 and are now called an Active Upgrade.
The Active Upgrade process is documented in the section Performing an Active MUF Upgrade in Datacom Core - 15.1
Review the documentation scenario entirely.
The upgrade process from Datacom/DB Version 15.0 to 15.1 is even simpler.
