Project talk: is translated as "$1-н_хэлэлцүүлэг" but it is wrong because it becomes "Wikipedia-н хэлэлцүүлэг". I assume this translation (suffix) is wrong, right?

It's technically correct, and works as a default, but as Mongolian words change based on grammar rules, if Википедиа was set as the project name, it would become "Википедиа-н хэлэлцүүлэг" - it should be "Википедиагийн хэлэлцүүлэг" (if that makes sense?)

What will it be for Wiktionary? The name is "Викитоль".

Is "Викитольгийн хэлэлцүүлэг" correct, or does it have to be something else?

Unfortunately, it's something else. For that particular case it's Викитолийн хэлэлцүүлэг.

Thank you. There's no need to say it's unfortunate, because there is a way to fix it. We hope to do it in a few days.

Thanks for that. I remember a time when this was configurable using MediaWiki messages, is any talk on making this configurable via, say, TranslateWiki?

Yes, before 2015 or so, it was possible to translate namespaces on translatewiki, but now it's disabled because it caused some technical issues. It may come back some day, but I don't know when.

Fixing this particular namespace is even more complex because it involves not just translating the namespace name, but also the site name, and combining them. However, it can all be done.

Output of namespaceDupes.php run. @srishakatux @Amire80, would you mind asking the community to review the few pages that were not migrated automatically: https://mn.wikipedia.org/wiki/%D0%A2%D1%83%D1%81%D0%B3%D0%B0%D0%B9:PrefixIndex?prefix=BROKEN&namespace=4? Thanks!

Thanks, @Urbanecm_WMF ! A few questions:

1. Did you also run it on mn.wiktionary? It's necessary there, too.
2. All the pages in the "BROKEN" list are redirects. Is it important to do anything about them? Should the redirects be deleted?
3. The only non-redirect page is Википедиа:BROKENОнцлох зураг. The title means "Featured image", but it looks more like a Main page. It doesn't seem to be linked from or transcluded in any other pages, but maybe it's because the broken title? The same title without the word "BROKEN" is Wikipedia:Онцлох зураг, which looks completely different, and still has the old "Wikipedia" namespace. Is this something caused by the script, or were those pages like that before the script ran?

Perhaps some of the "BROKEN" pages became like that because users created them in a "Википедиа" namespace before the namespace was actually configured, and the local administrator—who is the same person who created this task—moved them to the "Wikipedia" namespace, so they couldn't be cleanly moved to the new name because it was occupied by the redirect.

I just did now – no issues at that project:

1. All the pages in the "BROKEN" list are redirects. Is it important to do anything about them? Should the redirects be deleted?

Very likely not. The "BROKEN" pages are pages, which existed both with the old namespace and the new namespace. The script doesn't know which one is the correct one, so it kept both, and renamed one to include the word "BROKEN" as the prefix. They need to be compared with the corresponding page without the "BROKEN" word. If the content is same (or one is redirect to the other), deleting one of them makes a lot of sense. Technically, no action is required, but I do recommend someone taking a look.

Is this something caused by the script, or were those pages like that before the script ran?

Before the namespace change, there were two pages, Wikipedia:Онцлох зураг and Википедиа :Онцлох зураг. Apparently, they have very different content. As I mentioned above, the script didn't know which one to preserve (after the namespace change, they'd share the very same name, which is not possible), so it preserved both. At least one of them likely needs a rename.

One of them appears to have the old namespace still, but that is just because of cache. I purged it, and now the namespace appears as-expected.

Yes, this is likely what happened with those pages.

@Amire80 @Urbanecm_WMF I'll review any broken pages on Mongolian Wikipedia. Thank you for all the help!
