Updating, upgrading, and migrating your HMC machine code

Updates and upgrades are periodically released for the HMC to add new functionality and to improve existing features. Learn more about the differences between updating, upgrading, and migrating your HMC machine code. Also learn how to perform an HMC machine code update, upgrade, or migration.

When you are finished with each of these tasks, the HMC reboots but the partitions do not.

Upgrading HMC code
Replaces HMC software with a new release or fix level of the same program

Requires that you boot from recovery media

Migrating HMC code

A migration is a type of upgrade.
