Upgrading from Notes single user to Notes multi-user
While it is not possible to upgrade from a Notes® single user installation to a Notes multi-user installation during an upgrade install, you can use the supplied Notes® single user to multi-user migration assistant tool to migrate an existing single user installation to a multi-user installation within the same release and then run the upgrade install.
About this task
You can use a supplied tool to migrate a Notes single user install to a Notes multi-user install. The tool allows users to migrate from single user to multi-user for any release before upgrading to a new release.
