Hi,

Checked on Google and OTRS mailing list archives for an answer to this question but can"t find one.
I'm currently on the process of migrating to OTRS for a specific platform and in this way I was asked to restore back on OTRS all of our old Double Choco Latte tickets data so we wil have all historical tickets accessible through OTRS.

For the moment, I run into creating data in OTRS by sending custom mails containing old data and so let it create all necessaries entries by itself, so I'm using a lot all of these useful X-OTRS-* Headers BUT I wonder :

- is there any "hidden"/undocumented headers like X-OTRS-TicketID or X-OTRS-EmailDate ? It would help a lot because we need to keep Ticket Numbers the same between old and new ticketing system and for dates it would be better if we can keep original creation/modification/resolution dates from original emails.

- does anyone see a better way to integrate back all of these datas into OTRS ?

Thanks by advance for your answers.

Best regards,

Laurent
