[otrs] Howto use SQL to move tickets to new DB

Hi, I just migrated our OTRS instance to a new server, which included migrating the existing >80K ticket database. Then, sadly, over the weekend the cron on the old machine continued to fetch new tickets via incoming email, while agents entered new tickets by hand into new system. So, now I have new tickets in both systems and need to manually migrate 100 or so tickets in the old DB to the new DB. I'm sure I can do this by manually selecting tickets, articles, history etc and moving rows. I am hoping someone has experience, or a script to do this? Thanks in advance, MikeM
