find /dir | cpio -pvdm /new/loc

That *might* work.

find /dir -exec cp -p {} /new/loc \; -exec rm -f {} \;

That *should* work and might finish before you retire :).

#!/bin/sh

alpha=3D"a b c d e f g" # fill to z
ALPHA=3D"A B C D E F G" # fill to Z
digits=3D`seq 0 9`

for i in $alpha $ALPHA $digits do
  for j in $alpha $ALPHA $digits do
    for k in $alpha $ALPHA $digits do
      mv /dir/${i}${j}${k}* /new/loc
    done
  done
done

Add more layers if you need. You might as well use Python, PHP or Perl if
you can, though.

Also look at the bash manpage, I think there's a variable to change to
extend the default max # of arguments, but it probably doesn't go to 250k.
