Experts
I have a Distributed System (ABAP) like this
Server 1: Oracle Instace + SAP SCS
Server 2: Primary App
Server 3: Dialog Instance
Server 4: <Empty>
We are planning to do Hana Migration with DMO. We will install Hana on Server 4 (Empty). And after the migration the SAP instaces, will be pointing to the Server 4 with Hana.
Now, this will leave me with one Server running only the SCS instance (Server 1) because Oracle will be removed. Something like this
Server 1: Oracle Instace + SAP SCS
Server 2: Primary App
Server 3: Dialog Instance
Server 4: Hana
We don't want to use a server only for SCS, I am thinking we could move the Primary Application Instance to the Server 1 or move the SCS instance the Server 2
Server 1: Oracle Instace + SAP SCS + Primary App
Server 2: Primary App
Server 3: Dialog Instance
Server 4: Hana
Questions
Can I do this by uninstalling and reinstalling the SAP instances without touching the Hana DB?
Could I uninstall the Primary Application Server from Server 2 and install it again on the Server1?
If I want to uninstall the SCS, and install it on a different server.... Do I have to unistall the Primary and Dialog instance first and reinstall it after SCS is running?
