Downgrade from 11.1 to 9.10.2-U6

[Arun Gupta]

Is it possible to downgrade from 11.1-RELEASE to 9.10.2-U6? The 9.10.2-U6 is still showing up in the boot menu. Is it as simple as selecting this version and booting or do I need to do something else?

Thanks,
Arun

If you did not upgrade your pool to use the new feature flags then you should be safe to activate the earlier boot environment version and reboot without problems. See section 2.5.6 of the manual for information on pool upgrading and the associated potential limitations.

Even with an upgraded pool, providing you have not used the new ZFS features, you will be able to import the pool. If you have used the features introduced with FN 11, then the datasets utilizing them may be available as read-only.
