SEU packages are cumulative. The installation of prior SEU packages is not required before installing the current package. However, because SEUs are cumulative, issues identified in previous SEUs can require your attention when you import the current SEU. To review a cumulative list of recent feature updates and resolved issues since the last SEU you imported, view the Cumulative SEU Release Notes here.
SEU installation instructions can be found in the Cumulative SEU Release Notes on the Sourcefire Customer Support Site and in your Sourcefire 3D System user guide.
