+=head1 THIS SUCKS
+
+Yeah, this old Deprecated thing is a drag.  It can't do downgrades, it can only
+use a single .sql file for migrations, it has no .pl support.  You should
+totally switch!  Here's how:
+
+ my $init_part = ref $schema;
+ $init_part =~ s/::/-/g;
+ opendir my $dh, 'sql';
+ for (readdir $dh) {
+   if (/\Q$init_part\E-(.*)-(.*)(?:-(.*))?/) {
+    if (defined $3) {
+      cp $_, $dh->deploy_method->_ddl_schema_up_produce_filename($3, [$1, $2]);
+    } else {
+      cp $_, $dh->deploy_method->_ddl_schema_produce_filename($2, $1);
+    }
+  }
+ }
