Upgrading Drupal

Hi,

I updated Drupal to the latest recommended version 9.3.0 and I am facing issues for content types with an assigned comment field.

when I am trying to delete a node from such a content type, I get an error saying that there is no revision table for comments. I updated via composer and run database update without any errors.

node_revision__commentfield tables are available in my db fit that field. Has anyone else encountered such an issue?

I have a site based on Drupal 7 and I am upgrading to Drupal version 9.3 on my localhost.

I have installed:

1. Drush - 10.3

2. Composer - 2.1

3. Fresh drupal 9.3 installation

4. drupal/migrate_plus:^5 and drupal/migrate_tools:^5 and drupal/migrate_upgrade:^3 and they are all enabled.

5. Then I ran drush migrate-upgrade --legacy-db-url=mysql://DBUser:DBPass@localhost/DB --configure-only

6. Then I ran drush ms

And I got the error below-

I manually upgraded a tarball site from 9.2.6 to 9.3. Site ran fine except for SMTP email, as the vendor directory was replaced and the PHPMailer libraries were no longer installed.  I reinstalled the libraries with  composer require phpmailer/phpmailer  and the console output showed a bunch of components being downgraded to 9.2.6, including Drupal/Core!!  Sure enough, ran the status report and I was back to Drupal 9.2.6.

Error message:

Fatal error: Declaration of Symfony\Component\DependencyInjection\ContainerInterface::get($id, $invalidBehavior = self::EXCEPTION_ON_INVALID_REFERENCE) must be compatible with Psr\Container\ContainerInterface::get(string $id) in /usr/www/users/usr/website/vendor/symfony/dependency-injection/ContainerInterface.php on line 25

I've tried upgrading a Drupal 9 site, to 9.3.0

Not a user of Composer or Drush.

Hello

we recently updated a 9.2 Drupal site to 9.3.

Everything was fine except we hade more than 50 sync differences in configurations mostly in 

things like that

Where are the D9.3 files?

No, I do not use composer.

So, is this the end of my Drupal sites? I can not upgrade any further without code/files - or what?

Guess I have to go to backdropcms after all
