2 reasons, First, we can't do an upgrade because we know some of the
databases are not compatible with SQL 2005 so an inline upgrade won't work
for us. Second, Microsoft recommended we create another cluster group and
install along side the existing but we don't have the disk space on the
existing SAN and we are currently in an extreme budget crunch right now so
expanding is out of the question. So with no server money or SAN money we
talked about breaking the cluster and doing a fresh SQL install on the new
server once we took the passive node from the cluster. We should have
Active/Passive and not active/active/passive after it's done, right?

Why not keep the cluster and run SQL 2005 on there?.

Yes we are aware we lose the high availability. After we have the standalone
we are going to install SQL 2005 on the box and migrate our databases to the
standalone SQL 2005 box. After all the migration is complete we will
probably
kill the cluster and use the servers for something else. There was some talk
about possibly building another cluster later.

A cluster can run with even one node. What you are planning is quiteconstraints
feasible. What are your plans once you have the DB's on the stand-alone?
Keep in mind that on a stand-alone server, you lose the high availability
that you once had.

We have an Active/Active/Passive SQL 2000 cluster and budgetary
have made it impossible for us to upgrade the hardware to new servers. Ourmake
current servers are capable of handling the upgrade but some of our
databases
might not be compatible with SQL 2005. Can we evict the passive node,
it a standalone, upgrade it and then migrate the databases to the newserver
without killing the cluster? Will the cluster run if the passive node is
evicted?
