There are plenty of comments linking to meta.MO, which do not work after the migration. (The new url starts with tea.)

For example here:

Somehow my last comment disappeared... You might want to look at this thread on meta.MO and also here. — t.b. Apr 16 '11 at 23:34

Since some users who come to that topic might be unaware of this, I added a new comment:

After migration of MO to the SE network, the link from t.b.'s comment is: tea.mathoverflow.net/discussion/951/copyrights-at-mo — Martin Sleziak Dec 9 '14 at 17:12

I wonder whether this would be something we are allowed to bother moderators with.

I mean would it be ok to flag such comment and ask a mod to edit it?

Daniel Fischer

@MartinSleziak What is "plenty" (a good estimate will do)?

Martin Sleziak

Or would it be better to come here and mention the comment? (With the hope that some of the moderators who frequent this room will edit it.)

Or is it better to simply add new comments with explanation.

@DanielFischer That is difficult to say. I don't know whether there is SEDE query or something like that which would return all instances. (Only some of which are problematic.)

I am not suggesting editing all such comments en masse.

My question is what to do when I stumble upon such a comment. (Which might happen from time to time, depending how much I procrastinate on meta.)

Daniel Fischer

@MartinSleziak Why are only some instances problematic?

Martin Sleziak

@DanielFischer There might be links to the new meta.

Or can we distinguish them somehow?

Daniel Fischer

@MartinSleziak Ah, so the old meta was moved to tea, and a new meta was created?

Martin Sleziak

7:39 PM

Old link from t.b.'s comment: http://meta.mathoverflow.net/discussion/951/copyrights-at-mo/.

Link to a random post at new meta: http://meta.mathoverflow.net/questions/2105/encouraging-student-users.

So we can distinguish them - old links contain /discussion/ and the new ones contain /question/.

I did not realize it.

In that case, this could perhaps be automated.

Daniel Fischer

@MartinSleziak So it would probably urls with meta.mathoverflow.net/discussion/... and two or three other keywords?

Martin Sleziak

Yes, it seem that urls starting with that string are the ones in need of updating.

I thought that both links to old meta and new meta have the same format, so this cannot be done automatically.

I do not know whether we can search for them in some efficient way.

Daniel Fischer

@MartinSleziak Yes, either a redirect, or an automatic edit of the urls, as was done when Meta.so became Meta.se. I'll ask somebody.

Martin Sleziak

Another question is whether somebody from SE team can (and would be willing to) look into it.

I think there was feature-request on meta.

I found it:

Q: Update meta.MO links

This meta (and possibly the main site) had quite a lot of links to the meta.MO site, which is now replaced by a modern SE site. The previous meta was moved to http://tea.mathoverflow.net. Is it possible somehow to edit all the links (here and on the main) to meta.MO to point to tea.MO instead? ...

Redirecting meta.mathoverflow.net/discussion/.* to tea.mathoverflow.net is a better approach, as it fixes links on other sites too, and it's probably easier to implement. — Ayman Hourieh Jun 28 '13 at 23:46

I thought that we cannot distinguish the two types of links. But I was wrong. (So doing this manually is not the only possibility.)

@DanielFischer Thanks for your willingness to look into it. In any case, it is not an urgent matter. (Especially considering that the feature request is more than a year old.)

I just stumbled upon such comment, since and older question was linked in a recent one. That prompted me to ask.

@DanielFischer This query only returned 19 rows. But I do not see the particular comment I mentioned above, so there must be something wrong.

Daniel Fischer

7:55 PM

@MartinSleziak Well, I have no idea what SEDE may be missing. If there are only a few dozen, a manual edit would be feasible, though a redirect might be more elegant.

Martin Sleziak

Certainly, other sites might have links to old meta, too. So that would also solve the problem in other places.

(As mentioned in Ayman Hourieh's comment, which I copied here.)

Daniel Fischer

@MartinSleziak Ah, that query searches mathematics, not meta.mathematics.

Martin Sleziak

D'oh!

Daniel Fischer

53 rows.

Martin Sleziak

I will add a link to the query for meta.

And it also returned the comment I have mentioned.

BTW @quid added there a new link too:

A link above is broken. Here is the new version tea.mathoverflow.net/discussion/951/copyrights-at-mo — quid 24 mins ago

He probably got to that post from the same discussion.

In any case, if you have some means to bring that feature request to the attention of SE team, it would be nice.

Thanks once again!

Martin Sleziak

8:19 PM

I'll have to go now, see you later!

8:51 PM

I just feel incredibly stupid for not having seen that comment of @MartinSleziak; I removed my dupe comment.

Martin Sleziak

9:09 PM

@quid I don't think it would be a problem even if it stayed. In any case, as we were discussing links to tea and that particular post was an example, I thought that pinging you will probably not do any harm.

(I think I've done much stupider things on MSE.)

@MartinSleziak I am sure glad you told. Thanks.
