We were running our NW 7.0 ABAP+JAVA system on Windows 2003 and SQL 2005 . Somehow in some misscommunication the Network administrator has formated the system without taking the OS level image backup . This is our production system .
We did not take the system export before that .
Here is the situtaion :
He has detach the database and SAN . Install Windows 2008 and SQL 2008 . after this we have attached the database and SAN both ,
Now do we need to delte all the old SAP installation files from the SAN or we can just install the Central Service Instance and we will be good ? Do we need to do the rest of the instllation like Database Instance installation ,First MSCS Node ,Additional MSCS node etc...
What is the best way to install the SAP system on it with all the data . We have the data files and system files available with us .
Appriciate your quick help on this .
