Update: Implemented Jeffas suggestion ;)

Due to licensing costs (etc) for interfacing to SQLServer on anything other than a M$ platform - we decided moving to MySQL was the way to go. I could use the data exporter for any tables other than those that had text or blob style columns.

Consequently here is a program that handles each data pull/insert on a table by table basis. You need to update the SQL but that should be ok.

Note:
1) This is a Windows only app.
2) As I was dealing with BLOBS I had to restart the MySQL server with set-variable=max_allowed_packet=16M to stop it bombing on the larger sets of data.
3) I have already created the tables on the MySQL server. 
# Port from SQL Server to MySQL
use strict;
use warnings 'all';
use DBI;
use DBD::mysql;

use Win32::OLE;
use constant adOpenKeySet => 1;

my $db_datasource = 'driver={SQL Server};Server=HOST; database=DB;uid=
+UID;pwd=PWD;';
my $db_connection = new Win32::OLE('ADODB.Connection');
$db_connection->Open($db_datasource);

my $dsn = "DBI:mysql:database=DB;host=HOSTNAME";
my $my_sql = DBI->connect($dsn, 'me', 'julie', {RaiseError=>1});

# notice use of RaiseError - goodbye DBI::errstr!
my $table  = 'OTHER_TABLE';
my @field  = qw(ID description file_data);

my $rs = new Win32::OLE("ADODB.Recordset");
$rs->Open("SELECT * FROM $table", $db_connection, adOpenKeySet);

# Prepare our insert
my $insert_sql = "INSERT INTO $table ("
   . join(',',@field)
   . ') VALUES ('
   . join(',',map '?',@field) . ')'
;
my $sth = $my_sql->prepare($insert_sql);

while (!$rs->EOF) 
{
    $sth->execute( map $rs->{$_}{Value}, @field );
    $rs->MoveNext();
}

$rs->close();
$db_connection->close();

$my_sql->disconnect();

This should be good enough as a basis for any port tool someone else may need to write.
