Advice for specific subclasses of L<Catalyst::Engine> follows:

=head2 Upgrading the FastCGI Engine

No upgrade is needed if your myapp_fastcgi.pl script is already upgraded
to use L<Catalyst::Script::FastCGI>.

=head2 Upgrading the mod_perl / Apache Engines

The engines that are built upon the various iterations of mod_perl,
L<Catalyst::Engine::Apache::MP13> (for mod_perl 1, and Apache 1.x) and
L<Catalyst::Engine::Apache2::MP20> (for mod_perl 2, and Apache 2.x),
should be seamless upgrades and will work using L<Plack::Handler::Apache1>
or L<Plack::Handler::Apache2> as required.

L<Catalyst::Engine::Apache2::MP19>, however, is no longer supported, as
Plack does not support mod_perl version 1.99. This is unlikely to be a
problem for anyone, as 1.99 was a brief beta-test release for mod_perl
2, and all users of mod_perl 1.99 are encouraged to upgrade to a
supported release of Apache 2 and mod_perl 2.
