Note; this update is not required (and will not do anything) for versions > 1.7.x

This process can take a long time depending on database and number of threads.
Do not restart this upgrade if it times out.
Please open a support ticket on https://atelieraphelion.com to investigate to confirm the migration code will restart successfully.
