How to change the owner of objects

We have had a DBA leave us and I need to change the ownership of things in OEM so that we can maintain them and also remove this person's account.  The "reassign administrator objects" in the OEM UI isn't working even though it doesn't list any objects in the table that supposedly shows the "reasons" it can't reassign.

I've figured out the actual monitoring targets and have used `emcli change_target_owner` to change those.  But this doesn't work for non target objects like templates, incident rules, blackouts, patch/update components, etc.  I've yet to find an equivalent emcli command for these.  Obviously I could do "create like" for a lot of these thus creating new objects and then deleting the old (if it lets me delete them not being the owner), but that seems quite inefficient.
