Converting from Clarke_1866 to WGS_1984

Hey everyone.

I have to use the MCD12C1 products in an analysis. The problem is that this map is in GCS_Clarke_1866. I need it in GCS_WGS_1984. As far as I can see there is no conversion between Clarke_1866 and WGS_1984 when i try to use "Project Raster".

Therefore I when on the internet and found the following forum.

From here i get the impression that there is indeed no conversion between these two coordinate systems. However I also get the idea that a lot of Clarke_1866 data is really NAD_1927 or NAD_1983. Does this mean that I should just use define projection to convert to both of these? And then try to project each to WGS 1984 and see which fits best (fits best to a map that I know is WGS1984)?

 

How would you deal with this problem? 

Thank you very much!

Best regards
