Before performing an upgrade, ensure that the following prerequisites are met:
Any option that is configured through the nidpconfig.properties file will be overwritten after upgrade. Hence, ensure to back up the nidpconfig.properties file before upgrading to 4.3. After the upgrade, replace the new nidpconfig.properties file with the backed up file.
Access Manager 4.2 onwards, some of the options are supported only through the Administration Console. After the upgrade, you must configure those options through the Administration Console. For the list of options that must be configured through Administration Console, see Configuring Identity Server Global Options, Configuring ESP Global Options, Defining Options for SAML 2.0 in the NetIQ Access Manager 4.3 Administration Guide.
The upgrade process overwrites all customized JSP files. If you have customized JSP files for the Identity Server or the Access Gateway, you must perform manual steps to maintain the customized JSP files. For more information, see Section 8.1, Maintaining Customized JSP Files for Identity Server or Section 8.2, Maintaining Customized JSP Files for Access Gateway.
If you have customized any changes to tomcat.conf or server.xml, you must back up the files. After the upgrade, restore the files.
If you have installed the unlimited strength java crypto extensions before upgrade, you must re-install it after the upgrade because a new Java version will be used.
If you are using Kerberos, ensure that you back up the /opt/novell/nids/lib/webapp/WEB-INF/classes/kerb.properties file.
