Hey Peter, pocopico, I think I just found out the issue. The tinycore-redpill seems to have a regression with DS3617xs when using newer builds. You can see in the screenshots, when using DS3617xs, we are told that no drives are detected - I created a new esxi VM to test this out and i get the same message. once i switch to the DS923+ then i can proceed with installation or migration if i connect my DS3617xs drive to it. I am not sure if it's safe to migrate my DS3617xs to DS923+
