SAP HANA 2.0 and Multi SID installation

Hi All,

As we know HANA 2.0 is MDC by default hence I a have question concerning multi SID installation?

let’s say in an environment we have three standalone systems with HANA 1.0 SP12 (single dbs)and for these three standalone systems we have DR (disaster recovery) in one single appliance with multi SID installation (DR1,DR2 & DR3)

Hence when we upgrade our standalone systems to HANA 2.0 these systems will automatically converted to MDC then how about the DR system as this is a single system with multi sid I understand that we have to upgrade the DR systems as well to HANA 2.0 but my question is when we upgrade DR to hana 2.0 then this will also get converted in MDC meaning one single server will have three system dbs and 3 tenant dbs so is this supported?

As you know in multi sid each instance will have separate SIDADM user hence i have to perform upgrade on three instances separately on one single server so this will turn in to 3 system dbs and 3 tenant dbs is this ok? how hana 2.0 is getting Handel in multi sid scenario?

Initial discussion started here

I am posting this question here so that discussion will get more visibility .

Please shed some light on this.

Thanks

    You are correct. After the upgrade you will have three separate HANA installs with a tenant database on each of them. Your DR site should look exactly the same - three separate installs and a tenant database.

    Such installation is supported for both DEV and PRD environments, but please have a look to SAP Note 1681092 - Multiple SAP HANA systems (SIDs) on the same underlying server(s), as some restrictions apply.
