@JMoore96 We will need to merge this PR to fix those compile errors: https://github.com/PolymeshAssociation/Polymesh/pull/1322

I added a change to the storage_migrate_on macro to allow using a different name then StorageVersion for our storage versions. This will allow you to use PolymeshStorageVersion in this PR.
