You have to code it that way explicitly yourself, something like (UNTESTED):

my $file = 'Migration.cs';

open my $IN,  '<', $file       or die "Cannot open '$file' $!";
open my $OUT, '>', "$file.new" or die "Cannot open '$file.new' $!";

my $changed;
while ( <$IN> ) {
     $changed += s/class/xybpublicabc/g;
     print $OUT;
     }

close $OUT;
close $IN;

if ( $changed ) {
     rename $file, "$file.bak" or die "Cannot rename '$file' $!";
     rename "$file.new", $file or die "Cannot rename '$file.new' $!";
else {
     unlink "$file.new" or die "Cannot unlink '$file.new' $!";
     }

Thanks John!
I to edit it a little but it works!

Can someone explain to why I have to remove the $ from $IN and $OUT
and remove the "my" in "my $IN" and "my $OUT" to make it work?

Older versions of Perl could not use lexical variables for filehandles.
