SAP HA on Existing Environment

[Former Member]

Hii Experts,

We need to set up HA With MS SQLServer for one of our client's existing environment.In this case According to sap installation guide we need to use System copy of the existing database and then you can install your system with MSCS and then instead of loading the database from the Export DVDs in the installation package, you load it using your exported database.However I am not sure when we should load the exported database . Can some one please shed some light on this?

Thanks & Regards,
