L' Eomot Inversé (8/4/2013)
The answer seemed a bit obvious though - the phrase " Import Project Wizard" suggested that importing an SSIS project would be what was happening, and that seemed to exclude importing SSIS (not a project; I haven't a clue what that option could mean), upgrading a package, and importing a bunch of DTS packages which leaves just two possibilities.
Though I am on learning curve on SSIS 2008, still was able to answer based on same approach as used by L'Eomot. Nice to earn some points just from the common sense. :-)
