Prerequisites
=============

Before beginning an installation or upgrade, especially if timing is important, test to make sure you have the following:

#. SSH access to each CN (virtual) machine you will be working on.
    - if you don't have an RSA key, you may need to create one first, and save it to:
       https://repository.dataone.org/ ???

#. sudo privileges on each machine you will be working on.

#. ability to read the systems' password file located at: https://repository.dataone.org/documents/Projects/cicore/operations/source/pw/SystemPW.txt.gpg

    - you need to have:
      	  - gpg set up on your local machine
	  - a secure gpg key generated and imported into the GPG keyring 
	  - your public key submitted to svn in the pw/publicskeys directory, so your key can be used
            by others when they re-encrypt the SystemPW file.
         (see PWInstructions.txt in ./pw )

#. Make sure you will be able to have someone on-hand to adjust the round robin DNS - only DataONE Admins can do this.  You will need them at the beginning, middle, and end of the install / upgrade.
