Hi,

I've been struggling with upgrading from 9.5.11 to 10.0.0 for a few days now. I followed the instructions on https://www.drupal.org/docs/upgrading-drupal/upgrading-from-drupal-8-or-later/how-to-upgrade-from-drupal-9-to-drupal-10. 

At the first bugs,

Hi,

I am running Drupal 10 and 11 with different themes and I noticed that custom twig-tenplates are not preserved when updating the themes.

Is that correct behavior?

I would have expected that we could place custom templates in a separate folder where they would not be removed when updating the theme.

I did however not find any documentation anywhere about that.

So is everybody with Drupal sites just copying their own templates back into the system after an update? 

Would love to hear what others are experiencing on this front.

Hello,

I am trying to migrate a Drupal website from Drupal 7 to Drupal 10.4.1

The site has approximately 15,000 nodes with a large number of revisions (over 50,000).

I am working in a local environment where I have configured PHP and MySQL to allocate the maximum resources possible to improve the upgrade process.

However, the process is extremely slow. I can see the number of items processed per iteration decreasing like this:

I have updated my website from D9 to D11 version. After this update everything is working fine except one issue. And the problem is that when i am trying to add any new field to any of my content type the i am not able to do so. Getting this error:
TypeError: Cannot access offset of type Drupal\Core\StringTranslation\TranslatableMarkup in isset or empty in Drupal\Core\Plugin\DefaultPluginManager->doGetDefinition() (line 45 of core\lib\Drupal\Component\Plugin\Discovery\DiscoveryTrait.php).
