Hi Guys,
We would like to remove our current SAP J2EE CE 7.11 from our MSCS HA cluster and make it a standalone system, so we can perform an in-place upgrade of MS 2003 to MS 2008. Once the upgrade is complete we would then like to add this system back into a MSCS HA.
I was wondering if someone else has done something similar? I guess it boils down to two questions:
1. Can an SAP system be removed from a 2 x node HA cluster and run without issue on a single server? (HA option selected at install)
2. Can a fully installed SAP system running on a single server be turned in a HA cluster by adding the cluster services and an additional server?
I know export/import is the preferred option - but due to our landscape the above migration method is preferred by the business.
Regards,
Cillian,
