Hi,
Whatever script number it is erroring on on the setup page, to get past it you're going to have to chop that part out of the upgrade script.
Script files are located at:
/Setup/applications/mojoportal-core/SchemaUpgradeScripts/mssql
they are named by version number .config
Edit the file with a text editor and chop out the part it is complaining about.
Hope that helps,
Joe
