I have old version of Solr on one server. I have 4 Cores in it. I have installed new fresh Solr on new server. I have physically moved the old core directories as well, to new server Cores directory, but I cannot find a way to import them to new Solr instance.
How can I do it?

If you have an already existing Solr index and you want to try new settings, it is best to work and test on a copy Solr’s index first. Here are the simple steps to make a copy of your Solr’s index: Suppose we have already an index named cast and the copy will be named LuckBox.
<core instanceDir=”LuckBox” name=”LuckBox” />
Restart Jetty (e.g. sudo /etc/init.d/jetty restart)
Go to
http://localhost:8983/solr/LuckBox/admin/dataimport.jsp?handler=/dataimport
