= Description =

normal upgrade scenario for moinmoin would be to just copy the new version over the old one. this works fine, except interwikimap.txt. it gets overwritten. you don't notice this immediately, edit a page with custom interwiki links in it, then they disappear.

an upgrade should never break customizations.

== Steps to reproduce ==
## Describe the steps needed to reproduce the bug. If we can't reproduce it, we  probably can't fix it.
 1. add custom interwiki links to map
 1. use the custom interwiki link on maybe SandBox/TestPage
 1. upgrade moinmoin
 1. change SandBox/TestPage

--> your interwiki links are broken.


== Workaround ==
fixing is tedious:
 1. fix interwikimap.txt 
 1. fix the edited pages by changing them, save them and revert them to get rid of the broken interwiki links.

= Discussion =

See [[http://moinmoin.wikiwikiweb.de/MoinDev/InterWiki?action=AttachFile&do=get&target=MoinDigest876.txt]] for a possible way to solve this by
 * allowing interwiki map maintenance in wiki pages
 * separating between the "central" interwikimap page (part of moin distribution) and "local" additional interwikimap pages (maintained by wiki admins)

The distributed intermap.txt is the distributed intermap.txt, and it of course gets updated. Feel free to have a separate file with your own stuff.
