Instance multiple dialog instance at the same time

All,

I would like to have suggestions to install multiple dialog instance at the same time on different machines. My goal is to reduce dialog instance install time . Totally we need to install and configure 10 DI in a production enviroment at very minimal time.

This is on Linux. database is DB2

One approach we are thinkg is to install and configure a DI, and copy /sapmnt , /usr/sap//SID files from DI 1 to other DIs.

Please let me know if you think anything else.

Thanks!
