Currently, there is no migration path from Drupal 7 to Drupal 8 or 9. This is, obviously, problematic for all pages using the userpoints module that want to migrate from 7 to 8/9.
Since the userpoints module did not make use of entities in Drupal 7, it is not trivial how to handle the migration. For example, we need to decide into which point type the existing points should be migrated. A simple solution would be to create a default points type and migrate all of the points into that default points type.

Code: userpoints
Opened a merge request adding a first simple version of a migration routine that migrates all points into a default points type. It only respects the total userpoints (i.e., the userpoints_total table). That means that the log is currently not migrated. Feedback welcome!
