He will probably have to drop some (or all) the indexes, but it can be done; perhaps a temporary table which can be truncated? It might take some time otherwise, but this could be done at night by a batch program.
The important thing here IMHO is the file system, and whether this leads to fragmentation. With Windows, it would be a big problem. I believe Unix or AS/400 could handle this OK.
This is one of the reasons why you need a DBA for something like this!
