The closing step of a Nutanix Move migration, following data seeding, when chosen VMs switch over to the target. Downtime happens at this point and no other.

Terms in this definition
- Nutanix Move
Shifts files and VMs between hypervisors, say Hyper-V or ESXi over to AHV, keeping downtime low.
- Data seeding
While a source VM stays up, Nutanix Move duplicates its disks during this phase. Downtime comes only afterwards, at cutover.
- Virtual machines
Infrastructure-as-a-service compute giving complete control of the operating system, making it a fit for lift-and-shift moves and for software relying on OS-level pieces like COM.
- SWITCH
Checks one expression against several candidate values, returning whichever result pairs with the match (or a fallback otherwise). Writing SWITCH ( TRUE (), ... ) avoids nested IF chains: whichever condition is first true wins.
- OVER
Gives a T-SQL window function its window: PARTITION BY, ORDER BY and, if wanted, a ROWS or RANGE frame. Rankings and running totals can then be worked out while every row is kept.
Related terms
- Migration plan
Defines a group of VMs for Nutanix Move to seed, cut over and monitor. Creating one does not have to trigger cutover straight away.
- Storage Migration Service
Retires old file servers: this role inventories the source, copies its data, shares and security settings to a newer Windows Server or to Azure, then moves its identity across during cutover.
