Hi Stephen;

Yeah. The RT's all the same version, that's the easy part. Overlapping
tickets id (and attachments ids and transaction ids and user ids and ...) is
/the/ problem. Otherwise, it'd be a relatively simple sql insert dump.

To add insult to injury, we need to track ticket numbers that get changed,
such that urls to the "old" RT can be translated to their location in the
new "RT" via a custom web script.

Once someone had figured out how to use the API, I don't /think/ that this
would be such a difficult thing:

1) Get all queues, tickets, transactions, attachments, users, etc from old
RT. Stores these in a perl structure.
2) Switch connections to the new RT.
3) Loop through all of the above objects, inserting and modifying.

My essential question is: Is anyone willing to share code that does
something like this? Even just examples of actually using the API would,
imho, be incredibly useful to the community.

Much Thanks,

Isaac Vetter
