Old domain name in use after migration of site

Environment: local machine, OS X Lion, stock Apache and PHP.
DNS + AEgir installation according to Realityloop article: http://realityloop.com/blog/2011/10/25/mac-os-x-nginx-mariadb-php-aegir-... (NB. my DNS domain is *.dev)
I followed these instructions for importing a site: http://omega8.cc/import-your-sites-to-aegir-in-8-easy-steps-109

Steps I took:
- local Drupal 6.20 site upgraded to 6.26 + most recent version of all modules.
- imported site as platform and created www.mysite.dev as 'final' site name.
- followed instructions and migrated site to tmp.mysite.dev
- migrated tmp.mysite.dev back to www.mysite.dev.
- verified www.mysite.dev

The site page in AEgir still points to aegir.dev/hosting/c/tmp.mysite.dev

I was under the impression that this should also be changed.
