ArcGIS Pro 2.9 and ArcGIS Enterprise 10.9.1 are now available. For users planning to migrate their Roads and Highways environment from ArcMap to ArcGIS Pro, the attached migration white paper outlines the steps to migrate successfully.
There are also two python scripts that assist with the migration effort. You can find these tools at https://github.com/Esri/lrs-migration-toolset.
