Data migration implications for IP-based target portal group management

You must understand how target portal groups are affected before beginning the migration.

The following table describes the various online migration scenarios and how they affect your target portal group configurations:

Online migration scenario Impact to target portal groups
Migration between two systems running Data ONTAP 7.3.2 and earlier. No change

Existing interface-based target portal groups are not converted to IP-based target portal groups.

Migration between a system running Data ONTAP 7.3.2 or earlier and a system running 7.3.3 or later. No change

Existing interface-based target portal groups are not converted to IP-based target portal groups.

Migration between two systems running Data ONTAP 7.3.3 or later with interface-based target portal groups. No change

Existing interface-based target portal groups are not converted to IP-based target portal groups.

Migration between two systems running Data ONTAP 7.3.3 or later with IP-based target portal groups. IP-based target portal group assignments are preserved and there is no disruption in the iSCSI service.
Migration between a system running Data ONTAP 8.1 or later with interface-based target portal groups and a system running 7.3.2 or earlier with interface-based target portal groups. No change

Target portal group assignments are preserved.

Migration between a system running Data ONTAP 8.1 or later with IP-based target portal groups and any system with interface-based target portal groups. Target portal group information is lost and the iSCSI service might be disrupted.
