Upgraded to Suite but blog not upgrade

[anupam_luv]

I was having vbulletin 3.8.4 + vb blog, then I upgraded to vb forum 4.0 only (as evrybdy knows it doesnt hv blog).... so the blog data remained in the database ....
But then I upgraded it to vb publishing suite 4.0.... and still the blog data not upgraded, no blog posts showing yet.

I also have old vb blog (vbulletin 3.8.4+vb blog 1.0+) data and tried impex to import blog data from it but it not doing it ...
I tried the following options in impex

vBulletin Forum 2 Blog (3.6.8) ---> vbulletin suite cms 4.0

vBulletin Forum 2 Blog (3.6.8)---> vbulletin forum 4.0.*

But when I click check and update database it shows error on the last line

ImpEx will now Alter the tables in the vB database to include import id numbers. This is needed during the import process for maintaining references between the tables during an import. If you have large tables (i.e. lots of posts) this can take some time. They will also be left after the import if you need to link back to the original vB userid.
blog - importblogid Completed
blog_attachment - importblogattachmentid Completed

blog_moderator - importblogmoderatorid Completed
blog_rate - importblograteid Completed

blog_user - importbloguserid Completed
usergroup - importusergroupid Completed

usernote - importusernoteid Completed
customavatar - importcustomavatarid Completed
customprofilepic - importcustomprofilepicid Completed

The incorrect target to export to has been chosen for this source system, restart the import with a new session and select the correct version and system to export to.

Plz help me import old vb blog data to vbulletin publishing suite blog....
