In the current database model, an application combines several monitored services, which are then polled by assigning polling packages to locations.
In the new model, an application still combines monitored services, but in addition to this it also contains a number of references to locations. Furthermore, an application should also reference an optional polling package, which is used instead of the default if set.
The changes to be made include the Java entities, Liquibase changesets, create.sql and so on. An migration task is not required.
