You can't convert a PGP 2.6 key.  GPG will happily use it (within some  
limits, notably the IDEA cipher), but there is no way to convert it  
into another sort of key.

I'd recommend revoking any key that was generated with PGP 5.0.  There  
were problems with the random number generator in that version: http://www.cert.org/advisories/CA-2000-09.html
