Thank you for your reply! I knew it i just thought that it had such a strong pr (6) that it is a huge loss even if Google decreasing the focus from it. I also saw the authority metrics growing on the new domain which means that the new domain got some of its authority from the old. Perhaps we should wait another pr refresh. I tried to convince them to redirect the subpages to relewant new subpages but they wanted the hole previous version and the old domain to disappear.
Thank you for your reply!
