+Migration / Upgrade from Drupal 6 or 7
+--------------------------------------------------------------------------------
+An upgrade path from Nodewords on Drupal 6 or Metatag on Drupal 7 is provided.
+
+Two migration processes are supported:
+
+ 1. A guided migration using either the Migrate Drupal UI from core or the
+    Migrate Upgrade [2] contributed module. This will automatically create a
+    field named "field_metatag" and import any meta tag data that existed in
+    Nodewords on D6 or Metatag on D7.
+
+    This migration configuration is all prepared in
+    metatag_migration_plugins_alter(), the data is loaded onto the migrated
+    entity in metatag_migrate_prepare_row(), and then the data is remapped in
+    either \Drupal\metatag\Plugin\migrate\process\d6\NodewordsEntities or
+    \Drupal\metatag\Plugin\migrate\process\d7\MetatagEntities depending upon
+    what the source is.
+
+ 2. A custom migration using Migrate Plus [3] and possibly Migrate Tools [4].
+    This will require manually creating the meta tag fields and assigning a
+    custom process plugin as the source for its data. For example, if the name
+    of the field is "field_meta_tags" the lines fron the "process" section of
+    the migration yml file would need to look line the following:
+
+    For migrating from Nodewords on D6:
+--------------------------------------------------------------------
+process:
+...
+  field_meta_tags:
+    plugin: d6_nodewords_entities
+    source: pseudo_metatag_entities
+...
+--------------------------------------------------------------------
+
+    For Migrating from Metatag on D7:
+--------------------------------------------------------------------
+process:
+...
+  field_meta_tags:
+    plugin: d7_metatag_entities
+    source: pseudo_metatag_entities
+...
+--------------------------------------------------------------------
+
+    The important items are the "plugin" and the "source" values, if these are
+    not present the migration will not work as expected.
+
+    The data will then be loaded into the migrating entity using
+    metatag_migrate_prepare_row().
