VCenter 4.1 Error removing host

Hi,

I'm moving my hosts to a new vcenter.  I've moved the first host with no problems, but the second host is throwing an error.  See below.  Seems to be an issue with the database VIM_VCDB.

If anyone has suggestions that would be great.  I've tried searching on ways to simply reset the database or purge all of the data, but only found the method for 5.x which won't work for 4.x.

Thanks
