Lotus Domino Administrator 8.5 Help - Before you upgrade the Notes client

NOTES CLIENT INSTALLATION AND UPGRADE

Before you upgrade the Notes client
Before you begin upgrading IBM® Lotus® Notes® clients, make sure that you or your users do the following:

If the computer on which you are upgrading runs anti-virus software, close the application.
To successfully install, upgrade, and use Lotus Notes, users require Write and Modify permissions to the program directory, data directory, and all associated subdirectories.
If you are upgrading Lotus Notes on a Microsoft® Windows® system, you must have administrator rights to the system. Log in as an administrator or set administrator-level privileges for All Users. This can be done from the command line.
Notes installation on a Linux client is available as an RPM or DEB install package. The RPM install package is used on the SUSE and RedHat platforms, and the DEB install package is used on the Ubuntu platform. To use the RPM or DEB package, uninstall your existing Notes client using the ISMP uninstaller supplied with your installed release. Smart Upgrade is similar to the earlier ISMP method; the difference being the content of the update kit. An update kit for RPM or DEB contains several packages and a required shell script (setup.sh). See Lotus Tech Note 1314162 "Configuring for Lotus Notes 8.5 Smart Upgrade on Linux" for instructions and a sample setup.sh containing needed script statements. The Tech Notes repository is at http://www.ibm.com/software/lotus/support/notes/support.html. The upgrade kit contains both RPM and DEB packages. An example of script for both RPM and DEB is attached to this Tech Note.
You need administrative or root access rights to install Lotus Notes.
For cases in which administrative rights are not available, enable the setting "Always install with elevated privileges." The setting "Always install with elevated privileges" is a Windows setting that is part of Window's User Policies. Refer to your Microsoft Windows documentation for details. Refer to the Release Notes for the most current information on permissions required when installing as a non-administrator.
Options for installing the Lotus Notes client on Restricted or Standard/Power User computers are described in the Microsoft Windows Installer documentation.
Review options for customizing the Notes client installation and set up.
(Optional) Use the People - by Client Version view in the Domino Directory to quickly determine the Notes client version in use in your domains.
