We have an image service we overwrite every year with out latest imagery. We generate our own tile scheme in Pro when I go to analyze there's not errors but while the tile scheme is creating the caches we check the service and it says that there's a Incompatible with current basemap.
Update:
For anyone following or wondering. The issue was a clear projection mismatch. The solution was to create a referenced mosaic and set the coordinate system in the tool then use that to overwrite the image service. IT saves time from create an entirely new mosaic from the beginning.
SOLVED!
