SAP hana migration upgrades

Does system replication overwrite upgrades?

When i upgrade original primary and then secondary replicates to primary

Does my xs engine content get over written?

Delivery units versions are overwritten from replication?

Thanks!

Is there a process to gather all the delivery units from a fresh install and add them to a recovered install of same hana version.

Secondary is hana version 100 but recovered from hana version 97 making all the Hana delivery units of version 97

Primary is 97
upgrade primary to 100 Delivery units are version 100
Set primary as streaming replica

Fail over;
What are the New primaries Delivery units versions?

Solved all this noise below..

SUSE Linux Server 11 sp3

Hana upgrade from 83 to 101 (dev envirionment); 97 to 101 (production Environment);

Upgrade was successful after fail over to Streaming Replica..

When adding Hana version 101 as Replica of Primary(old replica).  The xsengine Content Folder would be over written; all packages /sap/hana/xs/admin, /sap/hana/xs/wdisp/admin; packages sap/* etc..
All overwritten with Primary (old replica, version 83,97).

I therefore would not get access to cockpit, wdisp, the new XS admin UI features..

I had turned off Statistics server way back during version 83.

When trying to re install Delivery Units after they were overwritten during Streaming Replication
Installation was failing for ZHANA_ADMIN.tgz,
Logs suggested that hana _SYS_STATISTICS schema and table was missing a field, After comparing this DB to a new install DB; the Field did not exist on the table as the logs mentioned.

NOTE 2006652

was of great help re initializing to the embedded statistics server.

After the process of getting statistics server running, I re ran hdbupdrep with --content_directory argument.

/hana/shared/<HANA SYSTEM ID>/global/hdb/install/bin/hdbupdrep


/hana/shared/HDB/global/hdb/install/bin/hdbupdrep /hdbupdrep \

--content_directory=/usr/sap/H2D/SYS/global/hdb/auto_content


This ran successfully and I was able to add ROLE

sap.hana.admin.Administration

to my user and see the /sap/hana/xs/cockpit


Hope this Helps People in the future.

Cheers,

Z
