I'll jump in & 2nd the motion on a straight *backup/verify-reinstall*
upgrade pathway. Once you decide to do that, it is no more difficult to
go from 4.2 --> 10.2 than it would be to go from 4.2 --> 6.2, except
that 6.2 is also past EOL & unsupported in the same way 4.2 is, so you
wouldn't be buying yourself any real advantage going to 6.2.
