We are running SAP 4.6 on Windows 2000 SP 4, etc. We want to upgrade to the latest SAP netweaver, on Server 2008 64 bit. Is the following a valid path.
Present SAP boxes to Hyper-v (2008 R2 flavor) VMs running Windows 2003 R2 64 bit (SAP 4.6), upgrade SQL to 2005. Do the SAP upgrade here. Then migrate the data/setup to a physical 2008 64 bit system.
Note: At no time would the VM's be used in production. They would simply be a waystation.
(And kudos to that Markus chap - I've read a number of your threads. Very useful!)
