Migrate from vtiger 6.3

[joebordes]

I just uploaded a change that may fix the fatal error. It is most probably due to an enhancement we added to sort the workflow tasks.

As to the errors I wouldn't worry about any of them except vtiger_ownernotify table. Make sure that table exists and you should be able to ignore the other errors.

Keep me informed.
