I moved the site from old host to new host.In the old host site was set up in a subddirectory like
and images are in mysites/site1/wp-content/upload folder
whereas on dreamhost,it has its own root
like mysite.com/wp-content/upload folder
image reference are still pointing to mysite.com/site1/wp-content/upload,how do i make it point to mysites/site1/wp-content in all the posts?
