How do I update Plex on 6.10.10 Firmware RN516?

Ok after downgrading the firmware to 6.10.9.  I went to the link to pointed out and message 37.  Then I edited the created the files needed easily using the Windows app "WinSCP".  It makes things a snap.  Docker CLI was then able to install once again.

Though my Docker apps were not running and I guess those containers gone?  I was able to pull updated versions, and create the containers once again and all my settings were still there.  I'm once again back up and running.  I got those 4 docker apps running once again.

I'm thinking about running all this stuff on a Mac Mini M1.  4 Low power and 4 high power CPU's and a good GPU.  I'm hearing some good things for 4K transcoding.   So I may end up going that route.

Still, a firmware update should specifically warn you that it is no longer allowing you to install any new apps and in fact is automatically uninstalling software.  Why is that?  First off, this shouldn't happen in the first place.  Let alone no clear big box WARNING on what is going to happen installing this firmware.  

It's firmware to make your ReadyNAS almost worthless. What is next for 6.10.11. firmware?  Deleting all your files and locking you out completely?  At least we have some help here to fix things. That is a big PLUS.  But it should never have been done in the first place.
