Hi,

I am currently trying to implement the upgrade path for the image encryption in Glance.

This should change all rows in the image_properties table where the names star with `cinder_encryption*` to `os_encrypt*`

The patch is: https://review.opendev.org/c/openstack/glance/+/926905

When I try to execute the data-migration on my devstack it does not work. I wonder why? What do I have to do to make it work?
Here is what I tried:

```
