I would need to find the best way to do a transition of domain name.
My initial thought was to cope the site, change references to.com, but hide from Google, but check uptime over a month to ensure that the server is stable. Then perform a perform a permanent redirect from.co.uk to .com.
I expect that I find information on the web about the best way to do it.
All references within a site should exclude the name [and be self-referencing].
So (for example) anything explicit:
<img src="http://my.domain/image.jpg">
becomes just:
<img src="/image.jpg">
