Models with a later database version will not be supported on a site with an earlier database version.
This scenario may occur when a model was created or opened on a Comparion site with a later database version, and you try to access the model on a site with an earlier database version -- either by:
- uploading the model, or
- opening the model when the sites are sharing the same database
Uploading such a model will show an error:
In case unsupported models are already in the model list, they have grey font color. You can hover on the model name to see details. 
In the examples above, the model version is 1.1.51, however, the site only supports version 1.1.46 (and lower), thus the model is unsupported.
To fix this, you need to create a copy of the model and save it to a lower version (in our example, to 1.1.46). Downgrading a model should be performed on the site which supports the current model version (1.1.51).
To downgrade a model:
1. Log in to the site where the current model version is supported (please contact us at support@experchoice.com if you need help)
2. In the Models list, right-click the model to downgrade or click the down arrow.
3. Click Save as... to open the save as options. Check "Save As Version" and then select the version you want to downgrade the model to, in our example, 1.1.46. You can also rename the model as desire. 
4. Click Save. The downgraded model will be at the top of the models list. 
You can hover the model to see details, here the model is downgraded to 1.1.46 (which is now outdated for this site).
5. Select the downgraded model and download it as a .ahps file from the Download button at the top. Make sure not to open the model as this will automatically upgrade the model back to the latest (1.1.51)
You can then upload the downloaded model to the site that only supports 1.1.46 and lower, or you can open it directly in case the database is being shared.
