thanks for your answer. Two questions:
- by "is not compatible": do you mean "is not in the compatibility list" or "there's a well known issue preventing ESXi 6.7 from running correctly on that HW"?
- Are you suggesting to try 6.0 for any specific reason or just a blind test?
As far as I know there is no way to easily downgrade (and I mean downgrade, not roll back) from 6.7: I should go through vconverter if it still exists/can convert from vmHW from 6.7 to 6.0.
1 - Such compatibility matrix specifies only the list of hardware that was tested and proven compatible.
2 - Because is the version that has been tested.
To elaborate on what Diego (correctly) points out:
- When you stray from the compatibility list, it becomes difficult to reason about what "should" and "should not" occur when problems strike. A common fallacy is often "if it works on 6.0 then it should work on 6.7." In reality there are massive changes between even point versions, so such an assumption is a guess.
- Going back to a version which is known good (by virtue of it being stated as compatible), you can rule out version drift. If the problem occurs in a known supported posture, then you have eliminated that variable and can try other troubleshooting methods.
