Also, the domain in question is listed in google and dmoz and is a .com. Is there any problem with transfering ownership with regard to these listings?
Thanks for any help
If the domain stays online and is not drastically re-purposed so as to need a different category, DMOZ and other directories should be no problem. However, if it goes "under construction" for a while, you could lose the listing.
Search engines index individual urls, not domains. If you take down the old urls then things could get crazy for a while. If you take the site as it is and expand on exisitng urls (perhaps phasing them out over time), you could have a very smooth search engine transition.
Under the circumstances, I am considering leaving the registration unchanged and just changing the nameserver entries.
Does it make sense for me to do this or may I just as well change the registration to me?
Thanks
