Can't run updates

hi
Can you please elaborate how you "Upgrade" to D10 ? For example what was the your previous Varbase version before you begin upgrade?

I had inherited the Varbase installation from someone else. When it was handed over to me, it was impossible to do anything with composer (including updates or new requires) because of a series of circular dependencies.
I brute forced by deleting the existing elements in the composer.json require and reinstalling current versions of everything, then running updb a few times. The site is now running nicely, but stalls on update 90006.

It's a hacky solution, but I added (temporarily)

if($name == 'field_yoast_seo_title' or $name == 'field_yoast_seo_description') {
             continue;
          }

to /web/core/lib/Drupal/Core/Entity/Sql/SqlContentEntityStorageSchema.php:hasColumnChanges and everything ran as it should.
