I hacked together a working conversion bot today. See for example

https://jira.toolserver.org/browse/PYWP-2

and

https://bugzilla.wikimedia.org/58820

The bots needs closing rights on the project on JIRA - the easiest is to add 'Bugzilla Bot Exporter (valhallasw)' to the admin group on https://jira.toolserver.org/plugins/servlet/project-config/<PROJECT KEY>/people

On the BZ end, the bot can set the assigned user, but currently does not have the rights to do this.

The bot only supports a single product/component/version, BUT takes JQL queries as input. If multiple products/compontnts/versions are required, this can be done by filtering the jira end using JQL and running the bot multiple times.

Process, as sent to toolserver-l:

Hello all,

Today, I hacked together a JIRA migration tool. If you want your bugs migrated please do the following two things:

1. Under Administration, <your project>, People, add 'Bugzilla Bug Exporter (valhallasw)' to 'Administrators' and click 'Update'. Otherwise, the bot cannot close the bug.

2. File a bug in bugzilla using the following link: https://bugzilla.wikimedia.org/enter_bug.cgi?product=Wikimedia&component=Bugzilla&cc=valhallasw@arctus.nl,marc@uberbox.org&blocked=58821&comment=Which%20JIRA%20project%20do%20you%20want%20to%20convert%3F%20(link)%0A%0AWhich%20component%20name%20(under%20%27Tool%20Labs%20Tools%27)%20do%20you%20want%3F%0A%0ADid%20you%20add%20%27Bugzilla%20Bot%20Importer%20(valhallasw)%27%20to%20the%20administrators%20in%20your%20JIRA%20project%3F

3. Your bugs will be migrated for you! See https://bugzilla.wikimedia.org/58820 for an example of what the converted bug looks like.

I would have hoped for a "nicer" result (i. e. that the bug looks as if it has always been in Bugzilla, with usernames & Co.), but - wow! :-) Thanks.

It's technically possible, but it requires command-line access to the bugzilla server. Andre mentioned he preferred this solution (as it's not clear what the security/stability implications are of imports via the command line).

I have improved on two things now:

• a different message format; instead of using the 'reply' format, use something more like a 'forward' format, i.e.

From: Merlijn van Deen <....>

Date: Wed, Jan 1 2013, etc

Message...

• linebreaks etc. are now converted. JIRA only hands a plain text version without any newlines by default. I now parse the html version of messages back to text.

There would also be the problem of JIRA functionality missing their counterparts in Bugzilla, e. g. resolutions "Answered", "Declined", etc., so definitely not trivial.

Whou. Congrats, seriously!
