OpenROAD images built with 6.2, 11.0, and 11.1 are supported by OpenROAD 11.2, but we recommend rebuilding to take advantage of new features. Releases earlier than 6.2 are not supported when deployed with a later runtime. For example, an image built in OpenROAD 3.5, 4.0, 2000 (5.0), or 5.1 cannot be used directly with OpenROAD 11.2.

The original source code used under these previous versions of OpenROAD may be imported into OpenROAD 11.2 and rebuilt so that images can be deployed with OpenROAD 11.2 .

Although an old image may work under a later version of OpenROAD with limited functionality, this is not supported or recommended. OpenROAD 6.0 and later versions check the image version and refuse to run to avoid accidental deployments.
