 ### SQL Graph
 
 - **Issue and customer impact**: Tools that are dependent on DacFx like import-export, will not work for the new graph features - Edge Constraints or Merge DML. Scripting in [!INCLUDE[ssManStudioFull](../includes/ssmanstudiofull-md.md)] may not work.
 
 - **Workaround**: Writing [!INCLUDE[tsql](../includes/tsql-md.md)] scripts and running them against the server using [!INCLUDE[ssManStudioFull](../includes/ssmanstudiofull-md.md)] or SQLCMD will work. Exporting or Importing database objects that create Edge constraints, have the new merge DML syntax, or create derived tables/views on graph objects will not work. Users will have to manually create such objects in their database using [!INCLUDE[tsql](../includes/tsql-md.md)] scripts.

 ### Always Encrypted with secure enclaves
 
 - **Issue and customer impact**: Rich computations are pending several performance optimizations, include limited functionality (no indexing, etc.), and are currently disabled by default.
 
 - **Workaround**: To enable rich computations, run `DBCC traceon(127,-1)`. For details, see  [Enable rich computations](../relational-databases/security/encryption/configure-always-encrypted-enclaves.md#configure-a-secure-enclave).
