Sun Enterprise Server Alternate Pathing 2.0.1 Installation and Release Notes

Backing Up Your Server

Always back up an existing server before you upgrade any software. The safest backup to perform is a level 0 dump (ufsdump(1M)) of the file systems connected to the server being upgraded. If you do not have an established backup procedure, see the System Administration Guide.

You do not need to back out installed patches before you perform the upgrade.
