Isn’t upgrading the TiDB cluster supposed to support rollback? The answers should be C and D, right?

I went back and watched the video, it seems that Teacher Dong misspoke, it doesn’t support rollback so I didn’t choose it.

Finally, someone who understands me. Sorry to say, but you said it out loud. :call_me_hand:

Thank you for the feedback. I misspoke when recording this question! The version corresponding to the course does not support rollback for TiDB upgrades. Option (D) itself is correct, but the question requires selecting the incorrect option, so option D should not be selected.
