Trying to migrate a simple site using Aegir. Source site is Drupal 7.66 and the destination is Drupal 8.6. The environment has an Aegir server with a remote web server (running both drupal versions) and a remote MySQL server. Migrating the website will keep the same MySQL server and web server.
The only change I see, other than the obvious Drupal platform change is that the old site lives under /var/aegir/hostmaster-7.x-3.174/sites/, and the destination will be /var/aegir/platforms/drupal-8.6.15/sites/.
Here's partial output from the migration attempt:
Any advice on where I can start to troubleshoot?
