  - Security considerations prior to upgrading
    It’s important to review your security practices before upgrading, especially if you are upgrading from an old version.
  - Preparing your environment for the upgrade
    Time spent doing a thorough evaluation of your environment prior to upgrading is time well spent. Capturing baselines of your existing server infrastructure allows you to compare how the upgraded environment is performing.
  - Planning the deployment of the new release
    Depending on the size of your organization and the number of Domino servers involved, an organization upgrade schedule may range from a few hours to a few weeks or months.

    - Notes client install best practices
      Follow these install best practices.
      - Multi-user installs
        Multi-user installs are ideal for most Notes users. The exception is users who use Domino Designer or Domino Administrator, which are available for single-user installs only.
      - Standard client installation
        Use the standard client rather than the basic client unless hardware is inadequate.
      - Roaming users
        Enable Notes users to roam so that settings and key Notes files (names.nsf, notes.ini, bookmarks, desktop, journal) stay synchronized across multiple clients.
      - ID vault
        If you don’t already, store Notes IDs in an ID vault.
      - Standardized notes.ini Settings
        Standardizing notes.ini settings across clients is recommended when possible by deploying the settings through policies.
      - Replicate notes.ini settings via roaming user functionality
        Enable roaming user functionality to push notes.ini settings replicated after an upgrade. Then, you can delete user notes.ini settings locally and roaming functionality restores them upon next launch.
      - Uninstalling before upgrading
        Uninstalling a prior version of Notes before upgrading is not required.
      - “Low touch” installation and setup
        Customize Notes installation and setup so that users aren’t required to input information into the install and setup panels (other than passwords).
    - Steps to deploy a new version of Notes
      The following steps are typical ones to use to deploy a new version of Notes in your environment.
    - Using Notes® Smart Upgrade and other upgrade tools
      You can push an upgrade to Notes® clients using Notes Smart Upgrade and/or other third party mechanisms, such as Smart Upgrade Run-As wizard (SURUNAS) or Upgrade-by-mail. You can also upgrade Notes clients using the Notes installation executable either silently (command line) or using the installer's graphical user interface. The supplied installation executable is used for an initial install or an upgrade install.
    - Maintaining Notes clients
      Upgrading Notes to the latest maintenance release and Fix Pack is a better choice than applying hotfixes

Uninstalling before upgrading
