I had a site setup on old-domain.com, which used the database old_db. Recently, we had to migrate our website to a new server and domain, new-domain.com which uses the database new_db.
I installed a fresh copy of wordpress to the new server, and using the wordpress import tool I was able to import all my posts to the current setup.The images did not copy over, so I simply copied over the wp-content/uploads folder to the new setup, and fixed the image urls using the plugin Search And Replace
Now the issue is, I have all posts appearing proper with images and everything. Everything except Featured Images. The site is not showing any featured images whatsoever. I was told that I need to copy over the postmeta data from old database to new one in order to correctly link them.
Both databases are on the same server. Any help would be hugely appreciated.
