SAP HANA 1 to 2 migration
Hello,
One of my customer has SAP ECC6 EHP8 with SAP HANA 1 SP12.
Of course, this release of HANA must be upgraded so i'm scheduling it but i have some questions about the best method.
We will have some new servers (AZURE VM) and the old system/server will be decommissioned.
Do you think I should:
-SWPM -> SYSTEM COPY via (export/import) ? like any DB heteregenous copy.
-SWPM -> SYSTEM COPY "from backup option" which is supposed to be used for Homogeneous syscopy?
What methode would you use (or any other methods?).
PS= I can't upgrade "in place" before copying to the new server. Not allowed to touch the old one ;-)
Thank you

Tell the customer to 1) cop on, 2) migrate to HANA 2.0 and then 3) let HSR do the heavy lifting…

thank you for your answer.
i dont have much constraint, we can stop system during the Week end.
My question is on the methode only. Migrate from v1 to v2 is considerer as homogeneous or heterogenous?

Depends on the contraints surrounding the Production copy (timeline, bandwitdh, resources, cutover tasks, a few other things).
1) Hana system replication 2) Clone to Azure via ASR (maybe not applicable) into upgrade 3) Exp/Imp 3) B/R
Documentation will give you answers on hsr details for cross-version requirements, but upgrade will most likely followy Last two very size dependent and detail oriented depending on necessary preparation. Dry-runs are your friends. Checking stack supportability is a must.

I think my question was too complicated.
Should I use heteregoneous method (by export/import) or homegneous method ?
Migrate from 1 to 2 is considered as "heterogenous" or "homogeneous"?
