My guess is that you are using 1.4.x and that the answer is no. The
only way to do this wholly transparent for the user with zero downtime
is by juggling over all volumes to another server and then add vicep,
upgrade OS and AFS (you probably should that anyway).

The 1.5 or 1.6 series will have the demand attach fileserver which
will give you fast restart (so fast that your clients will not
time out and then it would not be considered downtime).
