Overlapping 2 rasters using ARCGIS

I am trying to overlap 2 rasters (same region, but acquired in different dates). My objective is to know how much the soil changed after a landslide. I am using "Mosaic to Raster" to set Raster "AFTER_Clip" in the same spatial reference as Raster "BEFORE_Clip". The rasters have the following information.

 

BEFORE_Clip (before the landslide)

elevation info: EGM96

pixel size: 5m

data type: signed 16-bit

 

AFTER_Clip (after the landslide)

elevation info: WGS84

pixel size: 2m

data type: Float (32 bit)

 

I am probably doing something wrong because I am not getting satisfactory results.

If anyone can point me where I am wrong, or another better tool to use in this case I would appreciate it very much.

Update: when I choose the tool "Project Raster" the option "vertical" is not active. That means the rasters (DSM) do not have vertical coordinate system?
