Migrating to Drupal
At DrupalMaze we carefully scan all existing modules to both find out if they're being used, and determine if there's an upgrade path. Then we upgrade Drupal core, followed by one module at a time until the process is complete.
The final step here is cleanup of any issues encountered during the upgrade, and in many cases re-applying some configuration that got lost in the process. very essence is accessibility because it was made with a mobile first mentality—for users and end-users.
When site owners migrate to Drupal 8, they solve the need for an extremely responsive website. It's an upgrade that isn't an option anymore.
