Upgrade SAP HANA 1.0 to HANA 2.0

Hello Experts,

We will be soon performing upgrade of our existing SAP HANA 1.0 to SAP HANA 2.0 for ECC and BW systems.

We are checking below SAP provided notes for planning.
2372809 - Guideline for Upgrading a SAP HANA 1 to SAP HANA 2 System
2469025 - How-To Upgrading to SAP HANA 2
2115815 - FAQ: SAP HANA Database Patches and Upgrades

However, we have our production where system replication "syncmem" is used and hence we need some suggestion or strategy as how do we plan in such scenario. Any reference documentation? KBAs.

Also, if any SAP Notes which we should refer prior and after upgrade?

Appreciate your inputs.

Thanks.

    Hello Trev,

    As highlighted in below blog, break the system replication between primary and secondary, convert them into MDC individually, and reconfigure the system replication.

    https://blogs.sap.com/2016/05/25/convert-to-mdc-with-hana-system-replication-configured/

    https://wiki.scn.sap.com/wiki/display/SAPHANA/Multitenant+Data+Base

    You can also refer to SAP Note 1999880 and 2101244, where it is mentioned that the topology of primary and secondary site of a system replication scenario must be identical. As a consequence it isn't possible to replicate from non-MDC/single container to MDC.

    Hi Trev,

    Hana 2.0 is MDC by default if your Hana 1.0 is not MDC then during upgrade it will get converted in to MDC .

    Hence first you may disable the system replication and do the upgrade on Primary db and the do the upgrade on secondary db (dr site) and then reconfigure the system replication.

    Thanks
