Upgrading a UNIX system

When you upgrade a UNIX system, you have several installation options available to that platform only:

• Lotus Domino 6 supports multiple Domino installations on a single UNIX machine. You can run one earlier version of the Domino server on a computer with multiple Domino 6 servers as long as each Domino 6 server has a unique location.

  In earlier releases, Lotus Domino was installed in the opt/lotus location. You can specify any location for Domino 6 installation. If you choose another location and set the environment variable NUI_YESOPTLOTUS=1 before you install Lotus Domino 6, the variable creates a soft link to the location opt/lotus and backs up the previous Domino installation. Note that if you have an earlier version of Domino on the machine, the soft link to opt/lotus replaces the soft link of any earlier release.

• When upgrading an UNIX system to Lotus Domino 6, you can choose to install to the data directories only. This option upgrades existing server partitions on a UNIX system.
• With a UNIX system, you can use a script file to install Lotus Domino 6 on more than one server in the domain.

Upgrading a Lotus Domino server

Follow these steps to install the Lotus Domino 6 software on your servers.

1. Make sure you backed up all important Domino files.

For more information, see the topic Backing up files on a Domino server.

2. For all Domino Administration, Domino 4.6 MTA, and Domino 5 mail servers, make sure to prepare the server for upgrading.

For more information, see the topics Preparing to upgrade a Domino Administration server, Preparing to upgrade a Domino 4.6 MTA server, and Preparing to upgrade a Domino 5 mail server.

3. Install the Lotus Domino 6 software. If you install Lotus Domino in the same directory as the previous version, you do not need to make any changes to the server configuration. If you install Lotus Domino in a new directory, the program prompts you to configure the server.

4. During installation, select the server type.

5. After you install Lotus Domino 6, do one of the following:

• If you backed up your NOTES.INI file, replace the NOTES.INI file created during installation with the back up copy before you start the server. Then, start the server. The server will be set up automatically.
• If you did not back up the NOTES.INI file, start the Domino server to begin setup.
Note The Domino server installation does not include the Domino 6 Administrator client. You must perform a second installation using the client setup program to install the Domino Administrator. Install the Domino Administrator on a separate computer.

After you upgrade to the Domino 6 Domino Directory template, shut down the server to compact the database and rebuild the views.

7. Complete the post-upgrade tasks:

If you upgraded a Domino Administration server, see the topic Post-upgrade tasks for Domino Administration servers.

If you upgraded a Domino 4.6 MTA server, see the topic Post-upgrade tasks for Domino 4.6 MTA servers.

If you upgraded a Domino 5 mail server, see the topic Post-upgrade tasks for Domino 5 mail servers.

For all other servers, see the topic Post-upgrade tasks for Domino servers.
