I am not entirely pleased with my website's name and have been willing to change it for years. I feel it is not brand-able.
But since its an old domain name and overall figures of DA, PR, Moz score etc. are very good, I have been wary of changing the name and doing a 301 permanent re-direct from the existing name to the new one.
Please suggest me if I should go for it. If yes, what are the best practices to go about it.
