Is it a good idea now to upgrade to My Cloud OS5?

I’ve seen so many negative comments about My Cloud OS5 that I have been putting off upgrading my PR4100. Now I’m receiving emails from the My Cloud Team that support for OS3 will cease on January 15 2020 and that I must upgrade to continue to access my device remotely, I don’t know what impact that will have on running Plex but it doesn’t sound promising.

So is the consensus that OS5 is now completely fine to upgrade to, and all the issues that have been raised have more or less been addressed, or should I still hold out because of continuous issues ?

Wow…Just out of interest, do the My Cloud Team appear to be actively trying to fix these known issues with updates or is the whole this literally a hot mess?

Would it be a seamless transition to migrate my movie libraries over to Synology from Western Digital with minimal disruption to those accessing Plex over the internet ? Or would I need to go through the setup process again for each person?

I replaced all of my OS5-incompatible MyCloud devices (1 MyCloud, 1 MyCloud Mirror and two MyCloud EX2s) to synologys. Much better NAS. However, I upgraded my two OS5-compatible devices (MyCloud Gen 2s) to OS5 and after a couple of initial hiccups, they seem to be working OK.

I did not get to use the OS3. I started with the PR4100 just a couple of months ago. The system came with OS5. I have found the system to operate as expected. The system does seem a little mickey mouse but it does save files and deliver content to the internet.

Sorry I am not able to say whether OS5 is better or worse then OS3. I can say that OS5 has operated as I would expect a RAID 5 NAS to operate. Good Luck!
