Hi Bohyun, Thanks for v9. My points on v6 are all handled. Two new ones.
1. ICU rules are not copied. If the old template0 has daticurules, the new one has none and the upgrade still succeeds. A small fix is attached. 2. If a real run fails in the checks, the new cluster stays, and the same command then fails with "new cluster data directory is not empty". Nothing has been copied yet at that point, so could it be removed like in --check mode? Thanks, Shihao
