Fill holes in one raster from values from another raster via overlaying

Hello. I have a raster file with some holes in it (Picture 1) and i want to fill these holes from the value from another raster (Picture 2) via overlaying. Note that the resolution of the first raster is 100m*100m and the roselution of the second raster is 5m*5m. Is there a way to do it?

Have you looked at the Con tool

I don't know how to express the holes, as i guess they're different from NoData values..

Then you can reclass them to no data OR just use the Con tool if you know the class that you want to replace with the other raster's data. Principle is the exact same

Hi, I have the same problem where I am trying to fill the missing data (NoData) for my DSM with the values from my DTM. I am using the Con tool but I am getting an error message.
