Tough? No, if you know powershell, or can do some shell scripting. Tedious? Oh, yes.
Powershell can calculate md5/sha1 hashes, and for batch files, md5sum.exe
and sha1sum.exe exist.
Something like this:
for /f in (dir /s /b g:\) do md5sum %i > c:\batchfiles\output\out.txt
would get you started. Have to do proper quoting for names with spaces in
them, though.
The hardest part would be comparing the two lists - one from each machine,
especially with millions of files. You'd probably want to break it down
into directly-sized chunks.
