I'm trying to migrate my Umbraco database from 7.15.6 to 8.18.8.

I'm using a fresh empty installation and pointing it to my database, as suggested in the Proworks guide

However, I'm encountering several problems. Right now, I cannot continue with the process since I'm getting this error:

Value can't be empty or consist only of white-space characters. Parameter name: text

I've checked this post but I don't have any records in the umbracoNode table with an empty or null text.

This is probably just a matter of find where is this empty text and fix it, but I cannot find where it is without more information at least about the table.

This is the log:
