Just performed the update to it.
Well I downloaded it, unziped it, saved to local hard drive as instructed.
I ejected, using web interface, and unplugged my 12TB RAID5 USB3 4-Disk Vantec enlosure.
I clicked on the arrow to proceed with next step of update but was not even presented the option to use a local file.
No worries, It downloaded another copy then installed it and rebooted.
The Web interface is much faster that previous now but still takes several long minits to show the USB enclosure and shares. It is possibly faster than before but unknown since it’s been a while since I rebooted the device. Still slow.
Anyways, all my shares remain, all my users remain, and logins seem to be consitant with previous states.
My network only uses SAMBA.
FTP, SSH, Media Streamin, iTunes and notifications remain tuned off as I wish them to be.
I hope the disconnect issues have been resolved and if not I will post here.
So, to conclude, Go for it. The auto update worked fine, and no new problems have shown their ugly heads, and the WEB inerface is quicker. I have another 9TB identical enclosure and hope that I can use it with my USB powered hub now, I do not know yet. If it does function I am looking forward to backing up the files on the mycloud local drive to something with redundancy.
I hope my experience and this report helps somebody.
