I do not think there is a simple way to upgrade Wndows 2003 32 bit to Windows
2008 64 bit cluster. You have to be ready to create new 2008 cluster and
migrate all cluster data from 2003 (almost manually).

Subject: [ADSM-L] Windows Cluster migration/update and TSM
Hello!
I have some users that are upgrading their 2003 (32-bit) 2 node cluster to 2008
(64-bit) in the very near future. They plan on using the same two machines in
what is called an "in-place" cluster migration. Does anyone have any experience
with this?
I understand that the local hosts will probably do a full backup (no problem)
but I am concerned that the resource groups or attributes may be modified is
some way and generate a brand new back up. IBM has made it clear what could
generate a new backup, and it is understood, but it is the Microsoft side I am
unsure about. These resource groups hold more than 20 TB [Shocked] and I would
like any advise on how to avoid this please.
Thanks
