Migration: Renaming references with legacy enums fails
If a reference is to be renamed in the migration, the processor "update-reference" can be used:
<update-reference name="my.module:Type#ref" new-name="my.module:Type#ref2" />
The XML serialized model in the database is then checked to see whether there is a back reference to this reference in order to adjust it. This also happens if the target type is a classification (actually unnecessary, but to decide this the target type must be resolved).
If the target type in the XML file was a legacy classification (e.g.: "enum:tl.yesNo"), this fails because an attempt is made to find the "enum" module.
