Here is a small bug in the lastest importer. I was also there in 1.1.
When importing the queues, the queues in RT3 are not in the same order as in
RT2. The same queue does not have the same ID in both version . In my
instance, the first queue is Id=2.
When importing tickets, they go into the right queue, but when importing
"queue change" transactions, the original IDs are used instead of the new
IDs, resulting in corrupted information as to which is the old and the new
