However according to Den "newsfeed's entries contain an old domain name. Like "Someone commented on <a href='http://old-domain/photo-url'>your photo</a>". It's not so easy to convert it to new one as they are stored into the newsfeed cache. A complex sql query should be performed to apply new domain into newsfeed' entries URL. Create a separate topic on the forum and ask our support team to provide you with this query if you take care about it."
So can anybody shed any light on how to do this?
