About offline or in-service migration
- Offline
Servers are powered off before migration
Advantages: Faster migration time and partially-stacked domain support
- In-service
Servers remain powered on during migration
Advantage: Minimum downtime in server connectivity
All blocking issues, as identified in the compatibility report, are resolved
All acknowledgments are understood and accepted, including additional acknowledgments for in-service migration (for example, BIOS and SR-IOV)
A fully or partially stacked enclosure in a dual ring or left/right vertical stacking link configuration. See recommended stacking connections in the HPE Virtual Connect documentation.
Changes made during in-service migration do not take effect until the server is rebooted for the first time following the migration. Plan a reboot if an acknowledgment, such as an SR-IOV virtual function configuration, indicates a change that would impact your operation.
