System copy in MSCS environment

20 Views

Hi all!

We are in the process of upgrading our R/3 4.7x200 system to ERP2005 unicode. The upgrade and unicode conversion of Dev and Test have been successful, and now Production is next. By the way, we are not doing a combined upgrade and unicode conversion. The difference is that Prod is in a MSCS environment, while the other to are Central systems.

I have a question about how to perform a system copy procedure in a MSCS environment. As part of the Unicode conversion where I have to uninstall SAP (source and target systems are to be on the same hardware), and install it again as a system copy. I am wondering about the steps, and sequence of steps that needs to be performed in order to get the installation identical to what it is today. One node contains the Central Instance and the second node contains the database instance with MS SQL 2005. Do you have any tips for me?

I have recieved some information saying that I can perform the system copy as a Distributed environment, installing the central instance on one host, and the database on the other. My concern is that this will not fullfill the requirements for a cluster environment, where one node (node A) can failover to the other (node B) and vice versa.

Can you please advise on what the best option is and steps are?

Any input is highly appreciated!

Best Regards,

Thomas
