Chapter 20. Designing for nondisruptive upgrades 28320.1.2 Supported Data ONTAP upgradesSupport for system NDU differs slightly according to the protocols that are in use on thesystem.

Customers who are upgrading from Data ONTAP 7.3.2 can perform major version NDU to DataONTAP 8.0 and 8.1 releases. This is an exception to the guidelines for major version NDU.Customers who are running Data ONTAP 7.3 or 7.3.1 must perform a minor version NDU to7.3.2 before upgrading directly to 8.1.8.0 (and later) Yes Yes8.1 (and later) Yes YesSource Data ONTAP version Minor version NDUsupportedMajor version NDUsupported7.1, 7.1.1 Yes No7.1.2 (and later) Yes Yes7.2, 7.2.1, 7.2.2 Yes No7.2.3 (and later) Yes Yes7.3 (and later) Yes Yes8.0 (and later) Yes Yes8.1 (and later) Yes Yes
