In continuation of my previously asked question preserve-search-engine-index-while-shifting-to-new-domain. The migration is being done in the word-press and we will have same server with same IP.Since the database is same, all we did is export the data from old database to new database changed the link and now everything is perfect.
i know about that we can set 301 redirect in the .htacces file in wordpress but not sure how to do this, and since there are so many links in the old domain. i am not sure how best we can handle this redirect. Do we need to create a mapping for each old URL to new URL? and where we should put these mapping in the Old domain? any help in this regard will be much helpful.If i need to provide more information, please let me know i will put any other required information in post.
We are planning to shutdown the Old domain in next 6-7months once the new domain is UP.Is that a good decision? Additionally one more doubt which is there in my mind is about duplicate contents since both the old domain and new domain have 100% similar contents, so there might be some penalty from search engines.How can we handle that?
