Migrate items on Exchange Litigation Hold to EV?

You may want to be careful with the litigation hold because i believe that starts to use the Single Item Recovery, which can explode your exchange database sizes because every edit and change to a message is kept.

So if you have an item thats on single item recovery, you archive it, it goes to pending, then it gets turned in to a shortcut. So now you have three copies of the item, the original, the pending and the shortcut, so it can end up effectively increasing your exchange stores to 250% the original size

And in Journals as well, you get the same issue, the original item, the pending journal report, then the pending etc
