My client is forced to extract a substantial part of his websites content and place it in a separate context, that is not part of the original structure.
The current structure
The original domain has got a long-standing history, with a relatively good page-rank and many sites linking to it and it's contents.
The options are these:
place the site part in question to a subdomain of the origial one?
Create a new domain?
The contract didn't specify this in detail, and we'll lose some of the value of the original site, and we're looking into this because we want to minimize our losses. So, which one should be considered as 'best practice'?
