Hi, I have set up several sub-domains with their own functionality, but want to be able to share users from main_ prefix in the database.

The following works for default site settings.php

Currently running Drupal core 9.5.11 and am attempting to upgrade to 10.1.6. Unlike a previous post for Drupal 9.5.10, I am using Composer to perform the upgrade.

I have checked all Modules running on my site and they are up to date and compatible. I have backed up my site and database and attempted to upgrade using the following:

composer update "drupal/core-*" --with-all-dependencies

When I run this code I receive the following output:

We tried to upgrade Drupal from 9.5.10 to 10.1.6 upgrade gives error in core file

I have a site that has been running for about 10 years. I think it was Drupal 6. It was hacked up pretty good, and although I have *some* proficiency, it's been a long long time since I developed. 

The site finally completely broke, and I am unable to get into the UI. Homepage returns a 500 error. Nothing has changed on the site for at least 5 years.  I traced it down, and it looks like it is failing on a syntax error from mysql. It looks like something was changed or deprecated between mysql, and the database functions.
