ONTAP FLI

Migration types supported by Foreign LUN Import

FLI supports four main types of migration workflows: online, offline, transition, and automated. Your choice of which workflow to use depends on your configuration and other factors.

  • In an online migration, FLI from third-party arrays allows the client system to stay online during migration (requires a Windows, Linux, or ESXi host operating system).

  • In an offline migration, FLI from third-party arrays takes the client system offline and copies the data to the new LUN before bringing it back online.

  • In a transition migration, FLI transitions ONTAP operating in 7-Mode to ONTAP. This is functionally the same process except that the source array is ONTAP. The transition workflow is available in either online or offline mode.

  • In an automated migration, FLI uses workflow automation (WFA) software to automate parts of the migration process. FLI with WFA is available in either online or offline mode.

The differences between the workflows have to do with when cutovers occur, length of the disruption window, use of automation, or if the source array is a NetApp array running ONTAP 7-Mode or a third-party array.
