You cannot perform an in-place upgrade of Oracle Grid Infrastructure to existing homes. The same user that owned the earlier release Oracle Grid Infrastructure software must perform the Oracle Grid Infrastructure 19c upgrade.

Selected Answer: BCE
(Not F): "The same user that owned the earlier release Oracle Grid Infrastructure software must perform the Oracle Grid Infrastructure 19c upgrade." This formulation leaves open the possibility of having a user with a name other than 'grid'.

But I found now this, so E is really also good: https://docs.oracle.com/database/121/RILIN/procstop.htm#RILIN1173 => If you are upgrading the Oracle Clusterware or Oracle ASM software, then you must first stop all Oracle RAC database instances and all Oracle database instances that use Oracle ASM for storage. After stopping the database instances, shut down the Oracle ASM instances and Oracle Clusterware, as described in the following steps ...

between E or F, i agree with F "The same user that owned the earlier release Oracle Grid Infrastructure software must perform the Oracle Grid Infrastructure 19c upgrade." source : https://docs.oracle.com/en/database/oracle/oracle-database/19/cwlin/restrictions-for-oracle-grid-infrastructure-upgrades.html#GUID-76797070-C2C6-4817-902C-037A67A6EF94

I think it's BCF, cause the services are shutdown by the rootupgrade.sh: "The script shuts down the earlier release installation, replaces it with the new Oracle Clusterware release, and starts the new Oracle Clusterware installation." https://docs.oracle.com/en/database/oracle/oracle-database/19/cwlin/running-oui-to-upgrade-grid-infrastructure-from-an-earlier-release.html#GUID-3BE36DF3-EB62-4CD1-B53A-850A3E2129E3 While at the same time, F seems to be true since the upgrade can only be done by the same user who owned the previous installation: "The same user that owned the earlier release Oracle Grid Infrastructure software must perform the Oracle Grid Infrastructure 19c upgrade." https://docs.oracle.com/en/database/oracle/oracle-database/19/cwlin/restrictions-for-oracle-grid-infrastructure-upgrades.html#GUID-76797070-C2C6-4817-902C-037A67A6EF94

F is False. You run the installer software with the Oracle grid infrastructure installation owner user account (oracle or grid). https://docs.oracle.com/cd/E14804_01/doc/install.112/e10816/presolar.htm#CHDFAIBE

In a doc page for 12c, it's stated even more directly: "Oracle recommends that you leave Oracle RAC instances running when upgrading Oracle Clusterware. When you start the root script on each node, the database instances on that node are shut down and then the rootupgrade.sh script starts the instances again." https://docs.oracle.com/database/121/CWLIN/procstop.htm#CWLIN519

F is incorrect because in case of 'opatchauto', root is the user that can run the command. So, I think B is right because is about new version, that means OutOfPlace Upgrade. Upgrade can reuse an existing Oracle Base (C). And E for sure, because (at the moment) GI needs DBs from that node to be down. (E). So, most probably are B,C,E
