I'm guessing you are migrating volumes from the DellSC to the
DellPowerstore, in which case the problem is that the DellPowerstore driver
doesn't implement the update_migrated_volume method. Here is an extract
from [1] on the purpose of that function:

"This method can be used in a generally wide range, but the most common use
case covered in this method is to rename the back-end name to the original
volume id in your driver to make sure that the back-end still keeps the
same id or name as it is before the volume migration"

[1] https://docs.openstack.org/cinder/latest/contributor/migration.html

You might file a bug against the Powerstore driver. This is something that
Dell EMC would need to investigate.
