Reproject Raster

I'm working on a project and I need to reproject some rasters from NAD83 UTM to NAD83 SP. Easy enough. When I take a look at my original raster and my re-projected raster, I notice that they are not quite the same, however. As you can see in the screenshot. My original raster is on top (vc_mlw_sasthk in the table of conents) in black and white, my projected raster is on bottom (prj in table of contents) in a brighter color ramp and you can see it is not quite aligned with the original raster. You can also see that in some areas, the cell values have changed slightly (enough to make me worried).

My question: Anyone with experience in reprojecting rasters, have you ever run into this problem, and how were you able to resolve it?

 

I appreciate any ideas anyone has for troubleshooting/resolving this issue.

 

Thank you
