I ask this for freshmen like myself, and others, who want to make sure they are making the best migrate-update possible:
I have created a local copy of a Drupal 7 site and have also created a brand-new Drupal 8 site. I have no content to migrate-update into the Drupal 8 site besides Nodes, their Metatag data, and a list of Redirects. I've already installed the modules Migrate update, Metatag, and Redirect (via GitHub) in the Drupal 8 site as well.
Is here something special that needs to be configured after the installation and enabling of the module in the Drupal 8 site to which I plan to migrate and upgrade content?
In other words, should I configure something in the D8 site Metatag module settings to insure a stable and correct migration of each node's meta title, description, and keywords from the D7 site?
