Exporting and Importing Type Information
The type information in your system can be exported, and previously exported type information can be imported using the Windchill load framework. This can be useful both in your initial deployment, as well as when changes are needed in your production environment.
* 
When exporting and importing type information, the system from which you are exporting and the system to which you are importing must be at the same release level. Load files exported from a previous release may not load or work as expected.
Only previously exported type information should be imported. Manual editing of import load files is not supported.
For your initial deployment, the recommended strategy is:
1. Configure and verify your types, attributes, attribute layouts, and global enumerations in a test environment.
2. Export the type information from the test environment.
3. Import the type information into your production environment.
When changes are needed in your production environment, the recommended strategy is:
1. Export the type information from your production environment.
2. Import the type information into a test environment.
3. Reconfigure and verify your types, attributes, attribute layouts, and global enumerations in the test environment.
4. Export the updated type information from the test environment.
5. Import the type information into your production environment.

When a type is exported, the information included in the exported load files is the minimum information needed for the type to be successfully imported.
Measurement systems, quantities of measure, and reusable attribute definitions are not exported through this mechanism, except for the values used by a type being exported.
