Install and update KNIME Server nodes

KNIME Server
#1

I have a KNIME Server installed in a Virtualbox virtual machine.

  1. How can I install KNIME extensions, using the command line?
  2. How can I update the entire KNIME Server installation? I am running KNIME 3.4 and would like to update to 3.5.
