Hi Allan,
To transfer a Tickets to a completely different company you indeed need to copy it and then delete the old one.
Note that the application does provide ways to merge duplicate tickets and an option to merge duplicate accounts. So, if the reason you want to transfer the Ticket is because it was entered under the wrong Account, which has a duplicate one, you can use the
Account Merge option. This option will copy all Tickets to the "master" account and delete the "redundant" account.
I hope this helps.
