Maybe for JSON representations, we can use "JsonAnyGetter" and 
"JsonAnySetter" annotations to migrate old properties from 
representation classes. Problem is, that this approach is always a bit 
more work than keeping the old properties and migrate them directly.

Like for DB, we have 2 approaches for migrations right now:
1) MigrationModelManager, which is easier to use, but it requires that 
all the old properties are still kept on JPA and Mongo entity classes.
2) Liquibase and Mongo specific migrations, which migrates old data at 
DB level and doesn't require old properties to be kept. But it's pain to 
write migration scripts for them.

Maybe easiest is between minor versions to keep old properties and use 
the "easy" way of migrations, but for major versions, use the generic 
approach and get rid of all the outdated stuff from both JSON and DB?
