Well, I tried to backup,and it won't be possible because during the upgrade, since there were posts being made. They were being made using the same ID that old posts were using in the old database.
Luckily it was only a handful, but I do apologize to those who were affected. I totally forgot to turn on maintenance mode before doing it allowing additional posting to continue.
I was under the gun to get the site transferred that it just slipped my mind to turn it on.
