# MS SQL Server requirements

* A VM or physical machine with 2 cores or more, 4GB RAM or more, an OS &gt;Windows 2008R2 (not necessarily the server type), and 32 or 64 bits.
* The installation must be performed with an administrator profile on this machine.
* A Microsoft native ODBC driver for MS SQL Server with a 32-bit version must be installed.
* Requirements to capture an MS SQL Server source:
  * Express version is not supported.

  * The transactional replication component needs to be installed.

    To test the installation of the component, enter the following command:

    EXEC sp\_MS\_replication\_installed

    If the component is installed, the answer is: Command(s) completed successfully.

    Tables to replicate must have a Primary Key (Microsoft constraint).

  * You need to install on the VM or physical machine the SQL Server 32-bit client (ODBC 32-bit Native client driver). During the installation, the system MS SQL Server password (sysadmin right) is needed.
