In case of replacement for the DOM, we start to send DOMs that already have DSSv6 installed on it when we start to have EOL for the old product.

You can get all the builds you want for DSSv5 from :
http://www.open-e.com/account/products-and-updates/

If you need the direct link from our FTP, then you need to open a ticket so we can support it for you.

Note: support for DSSv5 will be ended at 31-MAY-2011.
