Save your changes and wait for MetaKube to add or delete your extra worker node(s):

The nodes will be upgraded in a rolling upgrade, which means it does a one-by-one upgrade of all machines. Therefore it will create a new node and when this node is ready will drain and delete an old node and so on until all nodes are updated.
