Most of the time you will use two servers, one for testing and the other for production. Therefore, you likely need to export models from the testing server and import it to the production server in order to use the models. Also, you might switch between test and production 3rd party systems, being mapped in Business Entities. This can be done, setting the right link usage
Export/Import
It gets difficult, however, because you don't want to import each model version as a brand new model, but as a new version of an existing model already on the production server.
Since exporting the model follows the same process as in a normal export scenario, we won't explain it here. Please refer to the Import/Export article for information on exporting models. On the other hand, importing a model from the testing to the production server differs from the standard procedure, when the model already exists on the production server, and you want to import a new version of the same model.
On the production server, click Import in the Publish tab under section Import/Export. In the opened window, navigate to the model you would like to import and click Open. Now you can select all models you want to import from the opened .fmex file.
Click Next to get to the screen where you can choose whether you would like to replace the old version on the production server with the new one or not. Use imported model means the old version on the production server is replaced by the new version from the import. The other option is the name of the model which has already been imported on the production server. You can also configure the model to be imported as a new version or not.
If all configurations are done click Next.
After clicking Next once more the import starts.
Clicking Finish closes the wizard. The imported model can be found under the Import scope in the sub-scope with date and time of the import.
