LGTM as long as it can never be used with an older oc.

LGTM as long as it can never be used with an older oc.

hmm, the pre-upgrade migration will run with 3.9 oc. I guess we should hold this until we branch release-3.10 and consider this for 3.11. It's just a warning of deprecation in 3.10, right?

[sdodson]

/hold

[enj]

Yeah the command just warns and ignores the user's input (confirm is always true).

/hold cancel

/retest
this will probably fail
