it's just a more compact way of showing the structure

try this 

use Data::Dumper;

# VERSION 1
my $ref_1;

$ref_1->{'1'}->{'test1'}->{'key1'} = '1';
$ref_1->{'1'}->{'test1'}->{'key2'} = '2';
$ref_1->{'1'}->{'test1'}->{'key3'} = '3';
$ref_1->{'1'}->{'test2'}->{'key1'} = '4';
$ref_1->{'1'}->{'test2'}->{'key2'} = '5';
$ref_1->{'1'}->{'test2'}->{'key3'} = '6';

$ref_1->{'2'}->{'test1'}->{'key1'} = '1';
$ref_1->{'2'}->{'test1'}->{'key2'} = '2';
$ref_1->{'2'}->{'test1'}->{'key3'} = '3';
$ref_1->{'2'}->{'test2'}->{'key1'} = '4';
$ref_1->{'2'}->{'test2'}->{'key2'} = '5';
$ref_1->{'2'}->{'test2'}->{'key3'} = '6';

foreach my $b1 (keys %{$ref_1->{'1'}}) {
    if(exists $ref_1->{'2'}->{$b1}) {
        $ref_1->{'2'}->{$b1}->{'1'} = $ref_1->{'1'}->{$b1};
    }
}

$Data::Dumper::Deepcopy=1;
