Last time this was debated here I pointed out that the upgrade from 4.x to
5.x will most certainly be less painful than upgrading from 4.x to 6.x (or
7.x, or 8.x) would be. That, in itself, is motivation to upgrade. Another
is that as time goes on and more people make the migration, fewer people
will be available to support 4.x.

Last time this was debated, someone posted instructions on how to have BOTH
versions on your server so that you can switch back and forth.
