|
migrate.pl - A script to migrate from other bug-trackers to Bugzilla.
|
|
|
|
|
|
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
|
|
|
|
|
|
./migrate.pl --from=<tracker> [--verbose] [--dry-run]
|
|
|
|
|
|
|
|
|
|
Migrates from another bug-tracker to Bugzilla. If you want
|
|
|
|
|
to upgrade Bugzilla, use checksetup.pl instead.
|
|
|
|
|
|
|
|
|
|
Always test this on a backup copy of your database before
|
|
|
|
|
running it on your live Bugzilla.

|
|
|
|
|
|
|
=item B<--from=tracker>
|
|
|
|
|
|
|
|
|
|
Specifies what bug-tracker you're migrating from. To see what values
|
|
|
|
|
are valid, see the contents of the F<Bugzilla/Migrate/> directory.
|
|
|
|
|
|
|
|
|
|
=item B<--dry-run>
|
|
|
|
|
|
|
|
|
|
Don't modify the Bugzilla database at all, just test the import.
|
|
|
|
|
Note that this could cause significant slowdown and other strange effects
|
|
|
|
|
on a live Bugzilla, so only use it on a test instance.

If specified, this script will output extra debugging information
|
|
|
|
|
to STDERR. Specify multiple times (up to three) for more information.

=head1 DESCRIPTION
|
|
|
|
|
|
|
|
|
|
This script copies data from another bug-tracker into Bugzilla. It migrates
|
|
|
|
|
users, products, and bugs from the other bug-tracker into this Bugzilla,
|
|
|
|
|
without removing any of the data currently in this Bugzilla.
|
|
|
|
|
|
|
|
|
|
Note that you will need enough space in your temporary directory to hold
|
|
|
|
|
the size of all attachments in your current bug-tracker.
|
|
|
|
|
|
|
|
|
|
You may also need to increase the number of file handles a process is allowed
|
|
|
|
|
to hold open (as the migrator will create a file handle for each attachment
|
|
|
|
|
in your database). On Linux and simliar systems, you can do this as root
|
2017-03-21 16:27:49 +00:00
|
|
|
by typing C<ulimit -n 65535> before running your script.
