Through the years I've successively upgraded my initial v4.7 unRAID install all the way to its current v6.3.5 version.

 

Today, I only just noticed that v6 now natively supports APC UPSs while the original third-party APC UPS plugin that installed way back in under v4 or v5 (can't remember) was no longer fully functional, so I decided to finally remove this discontinued plugin.

 

After doing so, however, the builtin APC UPS support lost communications with the UPS and rebooting unRAID does not resolve the issue.

 

Do I need to copy over a completely fresh 6.3.5?  Or is there a less drastic method of restoring builtin APC UPS communication support?

Try cycling power to the UPS itself

Unfortunately, this did not resolve the issue.

I ended up copying the entire contents of the flash drive, installing a freshly downloaded clean 6.3.5, booted it to verify UPS connectivity (it worked), then copied the old config folder over.

 

All now is good-to-go!

 

Though I wish there was a less destructive method...
