50006: Basemap layers will be converted to group layers in 9.3.1 packages

Basemap layers are only supported in ArcGIS 10, so they will additionally be converted to a group layer in the package to support ArcGIS 9.3.1 and ArcGIS Explorer. Basemap layers will remain a basemap layer when the package is opened in ArcGIS 10.


More information

The basemap layer conversion to a group layer will preserve the appearance of the map when opened in ArcGIS 9.3.1, but it will not maintain the high-performance interaction that basemap layers have in ArcGIS 10. For more information, see Working with basemap layers.
