Hi Team,
We have successfully migrated the Image Server from the old VM to the new VM (running on Windows Server OS). The Image Server has been validated with the Portal under the server sites, and the already published raster datasets are accessible and functioning correctly.

However, we are encountering an issue in ArcGIS Pro. When attempting to publish an image, the Image Server does not accessible - The selected server is not accessible.

Thanks & Regards,
Kristofer
