If the BusinessObjects Enterprise XI 3.1 installation program detects a simple deployment, where an entire product line has been installed on a single computer, you can perform a simple upgrade to BusinessObjects Enterprise XI 3.1. In a simple upgrade to BusinessObjects Enterprise XI 3.1, the installation program performs the following steps:
If you perform a simple upgrade to BusinessObjects Enterprise XI 3.1, the installation program automatically disables the previous BusinessObjects Enterprise XI system. After the upgrade is complete, the BusinessObjects Enterprise XI 3.1 installation program asks you whether to uninstall the previous system. It is highly recommended that you uninstall the previous version of the system as soon as you have verified that BusinessObjects Enterprise XI 3.1 SP3 has been successfully installed. If you choose to uninstall the previous version of BusinessObjects Enterprise later, you must ensure that the previous version's servers are not reenabled and not restarted. In particular, enabling the older version of the CMS and File Repository Servers will conflict with the BusinessObjects Enterprise XI 3.1 system.
If the installation program does not detect a simple deployment, you must perform a complex upgrade. This includes the scenario where your deployment's web and application servers are on separate computers.
The BusinessObjects Enterprise XI 3.1 installation program writes the details of your existing deployment to a log file. The name of the file is boe_up grade_output.xml; the boe_upgrade.xsl file provides formatting when you open boe_upgrade_output.xml. You can use this log file as a reference when you are configuring the servers and server clusters in your BusinessObjects Enterprise XI 3.1 deployment.
