Microsoft provides you with a robust set of script file commands and command line options to execute and control SQL Server Migration Assistant (SSMA) activities. The ensuing sections detail the same.

Project script file commands

The Project commands handle creating projects, opening, saving, and exiting projects.

`create-new-project`

Creates a new SSMA project.

Attribute	Default value	Description	Type
`project-folder`	None	Indicates the folder of the project getting created.	String
`project-name`	None	Indicates the name of the project.	String
`overwrite-if-exists`	`false`	Optional attribute, specifying whether an existing project should be overwritten.	Boolean
`project-type`	`sql-server-2008`	Optional attribute. The following options are available for `project-type`: `sql-server-2005` `sql-server-2008` `sql-server-2012` `sql-server-2014` `sql-server-2016` `sql-azure`	String

Syntax example

<create-new-project
  project-folder="<project-folder>"
  project-name="<project-name>"
  overwrite-if-exists="<true | false>"
  project-type="<project-type>"
/>

`open-project`

Opens an existing project.

Attribute	Default value	Description	Type
`project-folder`	None	Indicates the folder of the project getting created. The command fails if the specified folder doesn't exist.	String
`project-name`	None	Indicates the name of the project. The command fails if the specified project doesn't exist.	String

Syntax example

  project-folder="<project-folder>"
  project-name="<project-name>"
/>

Note

SSMA For Access Console application supports backward compatibility. You can open projects created by previous version of SSMA.

`save-project`

Saves the migration project.

Syntax example

<save-project/>

`close-project`

Closes the migration project.

Attribute	Default value	Description	Type
`if-modified`	`ignore`	Optional attribute to specify behavior. Possible values are: `save`, `error`, and `ignore`.	String

Syntax example

<close-project
  if-modified="<save/error/ignore>"   (optional)
/>

Attribute 'if-modified' is optional, ignore by default.

Database Connection script file commands

The Database Connection commands help connect to the database.

The Browse feature of the UI isn't supported in console.

The windows-authentication and port parameters aren't applicable when connecting to SQL Azure.

For more information, see Creating script files (AccessToSQL).

`connect-source-database`

Performs connection to the source database and loads high-level metadata of the source database but not all of the metadata.

If the connection to the source can't be established, an error is generated and the console application stops further execution

The server definition is retrieved from the name attribute defined for each connection in the server section of the server connection file or the script file.

Syntax example

<connect-source-database server="<server-unique-name>"/>

`load-access-database`

Used to load access database files.

Attribute	Default value	Description	Type
`database-file`	None	Specifies the path to an Access database.	String

Syntax example

<load-access-database  database-file="<Access-database>"/>

-Or-

<load-access-database>
  <access-database database-file="<Access-database1>"/>
  <access-database database-file="<Access-database2>"/>
</load-access-database>

`force-load` source or target database

Loads the source metadata. Useful for working on migration project offline.

If the connection to the source or target can't be established, an error is generated and the console application stops further execution.

Requires one or more metabase nodes as command line parameter.

Attribute	Default value	Description	Type
`object-name`	None	Specifies the name of the object.	String
`metabase`	None	Specifies the path to an Access database. Possible values are: `source` or `target`	String

Syntax example

<force-load
  object-name="<object-name>"
  metabase="<source/target>"/>

-Or-

<force-load>
  <metabase-object object-name="<object-name>"/>
</force-load>

`reconnect-source-database`

Reconnects to the source database but doesn't load any metadata unlike the connect-source-database command.

If (re)connection with the source can't be established, an error is generated and the console application stops further execution.

The server definition is retrieved from the name attribute defined for each connection in the server section of the server connection file or the script file.

Syntax example

<reconnect-source-database server="<server-unique-name>"/>

`connect-target-database`

Connects to the target SQL Server or SQL Azure Database and loads high-level metadata of the target database but not the metadata entirely.

If the connection to the target can't be established, an error is generated and the console application stops further execution.

The server definition is retrieved from the name attribute defined for each connection in the server section of the server connection file or the script file.

Syntax example

<connect-target-database  server="<server-unique-name>"/>

`reconnect-target-database`

Reconnects to the target database but doesn't load any metadata, unlike the connect-target-database command.

If (re)connection to the target can't be established, an error is generated and the console application stops further execution.

The server definition is retrieved from the name attribute defined for each connection in the server section of the server connection file or the script file.

Syntax example

<reconnect-target-database server="<server-unique-name>"/>

Report script file commands

The Report commands generate reports on the performance of various SSMA Console activities

`generate-assessment-report`

Generates assessment reports on the source database.

If the source database connection isn't performed before executing this command, an error is generated and the console application exits.

Failure to connect to the source database server during the command execution, also results in ending the console application.

Script

assessment-report-folder: Specifies folder where the assessment report can be stored.(optional attribute)
object-name: Specifies the object(s) considered for assessment report generation (It can have individual object names or a group object name).
object-type: specifies the type of the object specified in the object-name attribute (if object category is specified then object type will be "category").
assessment-report-overwrite: Specifies whether to overwrite the assessment report folder if it already exists.

Default value: false. (optional attribute)
write-summary-report-to: Specifies the path where the report will be generated.

If only the folder path is mentioned, then file by name AssessmentReport<n>.XML is created. (optional attribute)

Report creation has two further subcategories:
- report-errors (="true/false", with default as "false" (optional attributes))
- verbose (="true/false", with default as "false" (optional attributes))

Syntax example

<generate-assessment-report
  object-name="ssma.Procedures"

Script Generation script file commands

The Script Generation commands help save the console output in a script file.

`save-as-script`

Used to save the Scripts of the objects to a file mentioned when metabase=target, this is an alternative to synchronization command where in we get the scripts and execute the same on the target database.

Script

Requires one or several metabase nodes as command line parameter.

object-name: Specifies the objects whose scripts are to be saved. (It can have individual object names or a group object name).
