How to build SAP PAS for SAP HANA Disaster Recovery

[former_member482833]

Hello SAP Community

Below is our planned SAP production and DR layer on HANA database .

• Primary HANA DB
• Primary S4HANA Application ( CI/PAS)
• Secondary HANA DB( as DR)
• Secondary S4HANA Application ( CI/PAS)

I would like to know in regard with Disaster Recovery :-

• 1.Do we need to Install SAP system on Primary Server before setting up HANA system replication to Secondary HANA DB( DR) ? Do we first perform System replication enable first between Primary & Secondary DB & then install SAP system on Primary Server
• 2.To build the PAS/CI (application server) for Disaster recovery System . Do we need to export the Central instance & Kernel from Primary Production server) as per System copy export procedure
• 3.Do we need to do fresh install using SWPM on DR application host without DB instance installation as HANA DB tenant will already have ABAP schema if replication was enabled prior to installation.

Please note the HANA DB will be in replication asynch mode

Thanks & Best Regards
