title: How to migrate from MySQL to Galera Cluster
body: <p>I have a MySQL database with some data in it. Now I want to create cluster from this this database.</p>
  
  <p>I've already configured Galera, and I have just this single node. Now, how to replicate the data to ather nodes?</p>
  
  <p>Will it happen auto-maicaly by Galera, or should I dump current data first, then clean the DB on the first node, start all other nodes and load the data to one of them and wait for them to replicate.</p>
  
  <p>Following question is: how to add/remove nodes in runtime?</p>
