[rt-users] Recovering merged tickets

[mixo]

I recently imported data from rt 2 to rt 3 - 3.0.7_01 and then upgraded 
to rt 3.0.8. The
problem I have is that some merging seems to been undone - there about 4 
tickets that
were merged into 1, but that doesnt appear anywhere. Do I have to 
manually merge those
tickets, or can I run the import script again and set the following to 0:

 $import_global_metadata
 $import_users
 $import_groups
 $import_queues
 $import_tickets

and set $import_links" to 1  in the import script.
