Return true if current transaction is merge action.

Custom condition code:

my $txn = $self->TransactionObj;
return undef unless $txn->Type =~ /^AddLink$/i;
return undef unless $txn->Field =~ /^MergedInto$/i;
return 1;

If you need to refer to the original ticket id in a template it is available as $Transaction->ObjectId.

Variation:

Another Variation that says, if we are merging from a queue into a set of queues, and data from the merging tickets Custom fields need to be populated into the ticket your merging into..
