Upgrade to Xsan 2.3

137

Proceed through the setup assistant to the pane that offers to transfer data from an

existing computer, and choose to transfer data.
Connect the old computer and the new computer with a FIreWire cable, and restart
the old computer in target disk mode. You can restart in target disk mode by holding
down the T key when the computer starts up.
If you aren’t using FireWire to connect the computers, follow the onscreen instructions
for connecting them.

After the setup assistant finishes transferring data, proceed through the remaining

setup panes.

Shut down the old computer, and disconnect it from the Ethernet and Fibre Channel

networks.
The old computer has the same IP address as the new computer you migrated it to.
If SAN volumes don’t mount on a client migrated to Mac OS X Lion or Lion Server, use
the Xsan pane of System Preferences on the client to make sure Xsan is enabled.

Upgrade Mac OS X and Xsan:
Open the Mac App Store on the client computer you want to upgrade, and purchase

Mac OS X Lion.
After you purchase Mac OS X Lion, the Mac OS X Install Assistant opens. It upgrades
Mac OS X v10.6 to Mac OS X Lion, or Mac OS X Server v10.6 to Mac OS X Lion Server.
If the client computer you’re upgrading has Mac OS X or Mac OS X Server v10.5,
upgrade it to v10.6 before purchasing Mac OS X Lion. After upgrading to v10.6:

Use Software Update to update to the latest version of Mac OS X or Mac OS X

Server v10.6
Use Software Update to update to Xsan 2.2.1 or later. You must update Xsan because

there are underlying differences between Xsan 2.2 for Mac OS X v10.5 and Xsan 2.2
for Mac OS X v10.6.

Upgrading to Mac OS X Lion or Lion Server upgrades Xsan to version 2.3.
If SAN volumes don’t mount on a client upgraded to Mac OS X Lion or Lion Server, use
the Xsan pane of System Preferences on the client to make sure Xsan is enabled.

Upgrade Xsan only:
On a client computer with Mac OS X or Mac OS X Server v10.6, choose Software

Update from the Apple menu and update to Xsan 2.2.1 or later.
If the client computer has Mac OS X or Mac OS X Server 10.5 or earlier, you must
upgrade it to v10.6 in order to use it in your Xsan 2.3 SAN.

If Xsan Admin displays a message about “Incorrect Search Policy,” use the Login
Options section of the Users & Groups pane of System Preferences (the Accounts pane
in Mac OS X v10.6) to connect to the correct network account server (directory server).
