When upgrading from 7.0.3 to 8. our Post office's don't get the updated Database.

Is there a known issue?

I have shut down the entier GW system to do the upgrade, I have tried more than once but it still fails.

I can copy in the new db files and eventualy get it working ( although the latest atempt seems to be playing up.) but I want this to be a smooth change over.

We only have a small system, one domain and 2 PO's.

any ideas
