Upgrading Drupal

I have just upgraded from drupal 8 to 9 and backed up the database following the database update. I'm a bit concerned that the size of the resulting gzipped SQL file is a factor of 4 smaller than for previous drupal 8 backups. Has some material been removed from the database?

I'm trying to upgrade from drupal 8.9.17 to drupal 9, following the instructions at www.drupal.org/docs/upgrading-drupal/upgrading-from-drupal-8-to-drupal-9.... It went reasonably well but failed on running drush updatedb.

I made a complete copy of the drupal directory to a new drupal9 directory and applied the instructions to that. I had to change a few entries in composer.json to updated versions, but after that 'composer update' proceeded without any problems.

Currently trying to use the upgrade module to migrate site from drupal 7 to 9. stuck getting error "Failed to connect to your database server. The server reports the following message: SQLSTATE[HY000] [1045] Access denied for user 'drupal'@'localhost' (using password: YES)." even though I enter information correctly from settings.php file. I am able to use these credentials to log into the phpmyadmin site and access the database there but when I try to use the migrate module it tells me access denied. Any ideas on what could be the problem?

Hello All,

I am relatively new to Drupal as a whole and I am trying to update from 8.9.x to 9.2.2. Once I got through the whole process as laid out on drupal.org I tried to run the update.php to finish the upgrade, but I got this error:

An AJAX HTTP error occurred.
HTTP Result Code: 200
Debugging information follows.
Path: /update.php/start?id=2779&op=do_nojs&op=do
StatusText: OK
ResponseText: 

After proceeding to the error page I received this notice:

I've been using DrupalVM on my old laptop to create a migration from my Drupal 7 site to a Drupal 8 site. I'm running into several roadblocks but all in all I was able to run my script that does a clean site install in Drupal 8 and another script that migrates most of the D7 data over, one Drush migrate-import line at a time.

Good day everyone :)

I have a Drupal 8.7.6-site that should be updated. Since the site is not composer 2-compatible yet, I downgraded to composer 1.10.22, and tried to proceed the update. However, when I run I get the following error:
