Reversion and downgrade support

Beginning in Data ONTAP 8.0.2 7-Mode, you can revert to a Data ONTAP
release in an earlier release family or downgrade to an earlier Data ONTAP
release in the same family. You can perform these operations without
assistance from technical support when transitioning new or test systems to
earlier releases.
However, you must call technical support if you have problems during or
after upgrading. If you need to transition to an earlier release, see the Data
ONTAP 8.0 7-Mode Upgrade and Revert/Downgrade Guide to help determine the
correct action in your environment.

SSH server version for Data ONTAP

The SSH server version running on Data ONTAP is Data ONTAP SSH version
1.0.

Supported OpenSSH client versions

Data ONTAP 8.0.2 7-Mode and later releases support OpenSSH client version
4.4p1 only. To enhance security, OpenSSH client version 3.8p1 is no longer
supported because it does not contain the latest security fix.
