Data could be exported but the identity property is showing as disabled on the destination server? The issue is seen even after enabling the Enable Identity Insert? If you are experiencing above symptoms, I would like to inform that this is a by-design behavior. Repro Steps:
  • Exporting the data using Export Data utility:
                  1  
    • Select the Enable Identity Insert property and click OK.
                  exportutility_2               Complete data will be exported fine but the problem is as explained in below screenshots:  
    • Source Server – Identity property is enabled.
                  sqlserverexport_identity3  
    • Destination Server – Identity value is disabled. However, the data is present in the table.
                   export_4   The reason for the difference: When you create a table using export wizard it does not create the table with Identity attribute. Check the create table SQL statement under Edit mappings --> Column mappings --> Edit SQL. This SQL does not contain the Identity in the table creation script.                      identity_5   Approaches to fix this problem: Approach 1: Check the create table SQL statement under Edit mappings --> Column mappings --> Edit SQL. This SQL does not contain the Identity in the table creation script. You could add IDENTITY in the create table script as shown in figure below:                                                                 6   Approach 2: Generate the table script

             a. Right click on database --> Tasks --> Generate Scripts --> Select specific database objects --

             -> Select the tables you want to script out --> Check the properties in Advanced and enable/disable the property, if required.

                 Refer article - https://technet.microsoft.com/en-us/library/ms178078(v=sql.105).aspx          b. Execute this script to create the objects on the destination server. Approach 3: Use Import Data utility on Destination server to import the data. While selecting the options, please check the Enable Identity Insert under Edit Mappings option (refer below screenshot).                     7                     Validate the column properties to ensure Identity is enabled.   Related Articles: SET IDENTITY_INSERT - https://msdn.microsoft.com/en-us/library/ms188059.aspx Keep Identity Values When Bulk Importing Data (SQL Server) - https://msdn.microsoft.com/en-us/library/ms186335.aspx   Please share your feedback, questions and/or suggestions.
