DMV to check SQL Server edition specific feature

There are some features of Server Server Database Engine which change the way that Database Engine stored information in Database Files. These features are restricted to specific edition of SQL Server. If a database is containing these feature than that database cannot be moved to some other edition of SQL Server (Which does not contain that Feature).You can use below DMV to find all edition specific features enabled in the current database. 

SELECT DB_NAME() AS [Database Name], FEATURE_NAME AS [Feature] FROM SYS.DM_DB_PERSISTED_SKU_FEATURES

This DMV can check below four feature: 

• Change Data Capture 
• Data Compression
• Transparent Data Encryption
• Partitioning
