Re: Upgrading Windows 2000 cluster to Windows 2003 Cluster.

Been there, Done that.

Here is what I did:

First, I made absolutely sure I had all the drivers and software for Windows
2003, especially HBA and any multi-pathing software.
I then upgraded one node in-place to Windows 2003. Once I was sure it
worked as a cluster host node, I upgraded its peer node, also in-place.
Next was adding two new nodes based on new hardware. Note, you cannot add
x64 nodes to a 32-bit cluster. Once they worked fine, I removed the
original two host nodes and replaced them with two new ones that matched the
other new nodes.
Finally, I wiped the old nodes and rebuilt them as a new cluster on Windows
2003 for an entirely different purpose.
Started with 2 nodes and Windows 2000. Ended with 4 nodes and Windows 2003.
I also added a new SQL instance at the end.

Note that when you add or remove a node, you must re-run the SQL installer.
You must re-run any service packs and hotfixes after the install when you
add nodes. Read up under "Maintaining a Failover Cluster" in BOL for
instructions on adding or removing nodes.

I am planning to upgrade from Windows 2000 to a Windows 2003 Cluster. I
have
SQL server 2000 which we installed it as a virtual server.

We are doing a rolling upgrade and want to introduce new hardware at the
same time. Is it possible/recommended?
On the Windows 2000 cluster take one of the current servers off the
cluster.
Bring in a new Windows 2003 Enterprise server with new hardware and join
to
the Cluster. Do I need to install SQL server or when I move the cluster
over will the SQL server software get installed.

I greatly appreicated being pointed in the right direction.

Thank you ...Walter
