Error upgrading demo database to 8.8

Hi all

I am trying to upgrade one of my demo-databases but when I try the upgrade fails with an Internal Error (-10) on the object "Inventory Valuation Log" ...

because of the name I suspected that it might be because Iventory Valuation checkup have not been performed on the database... I ran the IVC script and it came back with the database being a candidate for a checkup....

My question is, could this be the reason for my upgrade fail (and if so is it really need to send all databases including internal test databases for IVC?)

I have allready upgraded other test-databases that did not have the IVC problem but does anyone know for sure if this is the issue
