Question on running multiple clients in production

[Former Member]

We have a question that hopefully someone might be able to clarify for us. We currently have a production SAP landscape consisting on 5 separate SAP clients running on five R/3 4.6c instances on RS6000/Informix and we are looking at alternatives around landscape optimization as part of a plan to upgrade to ECC6. One of the options we are weighing is to create a single SAP instance on 64 bit Windows 2003 Enterprise and SQL Server 2005, migrate the different clients onto the single system resulting in a single instance/multiclient configuration, and then to upgrade the consolidated server to ECC6. We have been researching the feasibility of this approach and it appears that it is a supported configuration (as per SAPNote 31557), however it is apparently not widely used and there are references to challenges with that approach. Wanted to see if anyone had experiences with this type of configuration and whether there are any specific showstopper issues that would make this unworkable as a solution.

Below is a list of some of the questions we are looking to address:

Can anyone cite a reference where a multi client single instance configuration was successful?

Can anyone cite a reference where a multi client single instance configuration was unsuccessful and the reason why it did not work?

Is there an upper boundary on the number of clients that can be supported in a productive multi-client instance?

Are there any specific issues with the CTS system that need to be considered

Are there any known issues with the ECC6 platform that need to be considered, especially with the potential deployment of a EP usage type and the J2EE stack?

Any known issues with upgrades after moving to a multi-client environment?

Were there any unexpected surprises (i.e. client independent objects that were not anticipated).

How was the issue of overlapping number ranges in different clients addressed?

Any feedback would be greatly appreciated.
