I'm trying to upgrade to 4.21 from 3.17. In the upgrade database part of the process I'm getting an error when it's trying to create the index mt_entry_authored_on on mt_entry:

"Error during upgrade: failed to execute statement CREATE INDEX mt_entry_authored_on ON mt_entry (entry_authored_on): Column 'entry_authored_on' is used with UNIQUE or INDEX but is not defined as NOT NULL at lib/MT/Upgrade.pm line 2595."

Any one have any Ideas as to how I can get around this?
