Welcome to the Q&A Forum

I have a client who has a website which is getting fairly descent traffic in the current industry its in. He is launching a new business model, same industry. New domain, new brand etc. Is it better to keep both entities separate and try growing them both? Or would it be more effective in terms of acquiring ranks and traffic to 301 redirect the old established site to the new site? Transferring all the value from the old and instantly boosting the new model. Not sure if this ads anything to the topic, the new domain is also an exact domain keyword match for a highly searched term.
