This is a great new tool. Thanks IBM.
"You can use the supplied single user to multi user tool to migrate a Notes
single user install to a Notes multi-user install for an existing Notes release
prior to upgrading to a new release. This enables you to convert an existing
Notes single user install to a multi-user install for both Notes basic and Notes
standard configuration deployments. It also enables you to convert a simulated
multi-user install (where the user's data directory is on a mapped drive) to a
true multi-user install. This tool is available for Lotus Notes 6.5.x, 7.x, and
8.x installations on supported Windows platforms only. "
