When attempting to open an older layout file in a newer version you may get the following error message:
The iModel layout you are attempting to load was created in a version prior to 6.4 and is no longer supported. Please reload this layout in any version from 6.4 to 10.01 and save it. You will then be able to load the new saved layout into the current version.
If you receive this error message contact the Helpdesk Support team and they can help you convert the layout. We keep an older version on 9.xx to assist with layout conversions.
