Upgrading Drupal

Hello,

I am new to drupal. I am trying to migrate a drupal 7 site to drupal 8. Followed the steps as stated on official drupal migration site using drush (https://www.drupal.org/docs/8/upgrade/upgrade-using-drush#s-basic-example). 

Here is my environment:

Drupal : 8.7.10

PHP: 7.3.11

Databse(MySQL): 8.0.18

My Drupal 7 database is on a remote server (not on same server as drupal 8). Here is my database config on setting.php.

One of my sites does not update properly with composer. I manually put in the new 8.4.4 core into web and then do:

Hello,

I am getting the following error messages from the data migration.

probably over 50 of these type:

Source ID 1924: No parent link found for plid '1917' in menu 'main'

a few of these:

Source ID 330: The path "internal:/departments/public-relations/press-release" failed validation.

Any idea how to resolve these?

I'm upgrading Drupal 7 to 8 using Drush and I received the follow error:

During updating with following commands:

 composer update drupal/core --with-dependencies
