Grid Infrastructure Upgrade from 12.1.0.2 to 12.2.0.1

Hello All,

We have to upgrade grid infrastructure from 12.1.0.2 to 12.2.0.1 on Exadata X5-2. This particular environment have multiple ACFS configured on which Golden Gate runs as well as couple of ACFS acting as standby ACFS (using ACFS replication from other Exadata X5-2 box where grid is 12.1.0.2 only and this will remain on 12.1.0.2 only). Both the Exadata box have been applied with April 2018 QFSD patch set for all components.

We need to ensure the ACFS & ACFS replication should be working as well along with databases and other related services post grid infrastructure. I am not sure but heard the configuration of ACFS replication is different in 12.2.0.1 compared to 12.1.0.2 including the commands to start the replication in 12.2.0.1.
