=head1 NAME

rt-importer - Import a serialized RT database on top of the current one

=head1 SYNOPSIS

    rt-importer path/to/export/directory

This script is used to import the contents of a dump created by
C<rt-serializer>.  It will create all of the objects in the dump in the
current database; this may include users, queues, and tickets.

It is possible to stop the import process with ^C; it can be later
resumed by re-running the importer.

Certain records (notably queues and groups) will have their original
Organization name prepended to them on import. This is primarily to avoid
duplicate names (for example importing a General queue into an RT that
already has one would otherwise cause a name collision error). If you are
confident you won't have any name collisions in queues or groups, you may
suppress this behavior by passing the B<--exclude-organization> flag to
C<rt-importer>.

=head2 OPTIONS

=over

=item B<--list>

Print a summary of the data contained in the dump.

=item B<--originalid> I<cfname>

Places the original ticket organization and ID into a global custom
field with the given name.  If no global ticket custom field with that
name is found in the current database, it will create one.

=item B<--exclude-organization>

Ordinarily certain records (groups, queues, the B<--originalid> custom field)
include the organization name of the original RT instance. Use this option to
suppress that behavior and use the original name directly.

=item B<--ask>

Prompt for action when an error occurs inserting a record into the
database.  This can often happen when importing data from very old RTs
where some attachments (usually spam) contain invalid UTF-8.

The importer will pause and ask if you want to ignore the error and
continue on or abort (potentially to restart later).  Ignoring errors
will result in missing records in the database, which may cause database
integrity problems later.  If you ignored any errors, you should run
C<rt-validator> after import.

=item B<--ignore-errors>

Ignore all record creation errors and continue on when importing.  This
is equivalent to running with C<--ask> and manually typing "ignore" at
every prompt.  You should always run C<rt-validator> after importing
with errors ignored.

B<This option can be dangerous and leave you with a broken RT!>

=item B<--dump> I<class>[,I<class>]

Prints L<Data::Dumper> representations of the objects of type I<class> in the
serialized data.  This is mostly useful for debugging.

Works only in conjunction with C<--list>.

=back


=head1 CLONED DATA

Some dumps may have been taken as complete clones of the RT system,
which are only suitable for inserting into a schema with no data in it.
You can setup the required database state for the receiving RT instance
by running:

    /usr/sbin/rt-setup-database --action create,schema,acl --prompt-for-dba-password

The normal C<make initdb> step will B<not> work because it also inserts
core system data.
