Well we tried it in a test environment. It does not work. If you downgrade from v8 to v6, the iscsi target and device info are all wiped out.

Hello,

My SAN is dramatically slowed down after upgrading from V6 to V8. I am getting 6-10MBPS while I was getting 80-120MBPS on a Gb network.
The question is can I safely uninstall v8 and reinstall V6?
Thanks.
