Powerpath upgrade in RHEL 7

Hi All,

I need to upgrade powerpath from 6.4 to 7.2 on my Redhat linux 7.9 host.

As per the EMC upgrade procedure "Unmount any file systems that are mounted on PowerPath devices and deactivate any volume groups using these file
systems". 

My system uses powerpath devices for all volume groups including rootvg. I can export non-root vgs and remount /boot partition using uuid but I am not sure how to disable rootvg filesystems, will it cause any issue for the upgrade.

could someone please help with the procedure on this.
