Right now I'm running NW6.5 SBS on two servers - one file/print/vo and one
GW6.5/web/backup and I'm planning on updating to a clustered enviroment with
new hardware. So, in an enviroment with no more than 60 users is a 2-node
cluster acceptable for failover or would it be wise to add a third node for
just failover?

Also, I know you get a 2-node license with SBS, but is there a restriction
from purchasing/implementing the third license?

Finally, would I set up the cluster, then use the SCU to migrate the data or
is the migration wizard an option?

Any help on this would be of great help. Thanks in advance.
