migrate yahoo mail china to yahoo mail us?

[Charlie]

hi,
I have an email account at yahoo.com.cn and recently received an alert when I logged into the account which told the yahoo china mail service would be shut down and the procedure of migrating to yahoo us. As I was busy doing something else, I didn't do the migration at that time. but now I can not find the info again, could any one tell at where I can find the info?
thanks in advance.
many thanks to Trooper63 and Darcy Fitz provide your answer to the question, especially Trooper63 listed a lot of information on yahoo service. although these info do not directly solve the problem, thanks anyway.
I find the info after spending quite a few time searching the web, the link listed below for reference to people who have same issue as I do.
