Upgrade to 13.0 from 12.0.2 fails to convert all Discussion Postings to Rich Text
Just noting here but my question is more of a why does this occur? Solution is relatively easy. Discussion comments appear with ???name??? like this:

Solution is clearly documented by article CS436187: https://www.ptc.com/en/support/article/CS436187?source=search
I have over 201K comments in my system but when I rant the check query the article described, 40000 remained. Its too round of a number to be believed so what's going on here? I suspect its some query limit but not sure where.
I ran the update command to fix and it left 10000 incomplete. Another nice round number. Running a second time brought it down to 0. Strange that the upgrade script marks it as done and moves on. Also interesting that the fix is running a loadFromFile xml command. I've not seen that done before. Strange way of invoking a utility.
windchill wt.load.LoadFromFile -d loadFiles/upgrade/updateMessageToRichTextMigrator.xml -u wcadmin -p password
anyone know how the above command works? Seems like you can tell it to do anything.
