It's easy to do. If you have a fileserver at address 1.2.3.4, and
another fileserver at address 1.2.3.5, and issue

vos changeaddr 1.2.3.5   1.2.3.4

you've now got an MH entry for 1.2.3.4 and an old-style entry for
1.2.3.4. You can even have multiple old-style entries that way;
VL_ChangeAddr doesn't check the 'destination' IP address pretty much at
all.
