In the end the solution is very simple and proves why LLBLGen is so powerful and easy to use.
First of all. When you generate your entities the catalog name is stored in FieldInfoProviders. This can be retrieved with following instruction:
var catalogName = ORMapper.Utils.DatabasePersistenceInfo.GetFieldPersistenceInfo(ArticleFields.PKey).SourceCatalogName;
This catalog name is the catalog you used to generate the entities against. This is probably your development database.
Next thing you do is map the development catalog name with the production catalog name. Like so:
adapter = new DataAccessAdapter("Your connection string");
adapter.CatalogNameOverwrites =new CatalogNameOverwriteHashtable();
adapter.CatalogNameOverwrites.Add(catalogName, "ProductionCatalogName");
