Conversion to Microsoft cluster

[Former Member]

Our Prd system is running R/3 4.7 ext 1.10 on Win3k/SQL2000. We would like to convert the Prd system to a MS Cluster enviroment by adding another new hardware. My planned steps are:

a. Detach/backup the database from the Prd

b. Setup the cluster - uninstall SAP in node a (old server) and node b ( new server ), hardware SAN, network prep, etc.

b. Reinstall a new SAP installation with the SAPinst cluster options in node a & b

c. Attach/restore PRd db to the cluster.

This is my understanding from the SAP inst guide and notes.

Is there any other method in step (b) where is could "convert" or "migrate" the SAP instance/MSSQL data without reinstalling ?

For SAP instance you have to use options:

>b. Setup the cluster - uninstall SAP in node a (old server) and node b ( new server ), >hardware SAN, network prep, etc.

>b. Reinstall a new SAP installation with the SAPinst cluster options in node a & b

as there is not any direct way to convert existing SAP instance into MSCS - installation has to create services on both nodes, common file system, set the appropriate environments etc.

The same is for DB. You have to put DB (also master) on shared drives and you can achieve this only during the new installation and detach/attach routine for SAP DB.
