Undo merge or create redirect to new URL

[Duken]

Damn, i did something stupid. I merged an old topic to the new one..... Wrong way  this old topic is very populair on google. Now the topic is gone and i wish i could undo this.

I think you cant undo a merge. So i need to redirect the old URL to the new topic id / URL.

How can i do this?! Hope there is someone with a Solution..... Regards!

Is there a good way to do a 301 with a .htaccess file for one forum URL? Or can this break more?

Google “htaccess redirect single page”

[Duken]

Well it looks good  . I could find that @opentype ?

For visitors: My new .htaccess file (bold) is added. I added two because of a rename of the topic.

<IfModule mod_rewrite.c>
Options -MultiViews
RewriteEngine On
RewriteBase /forums/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule \.(js|css|jpeg|jpg|gif|png|ico)(\?|$) /forums/404error.php [L,NC]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /forums/index.php [L]
redirect 301 /forums/topic/35332-formule-1-op-pc-kijken-via-streams-zonder-ziggo/ /forums/topic/36172-formule-1-2018-kijken-via-live-streams-zonder-ziggo/
redirect 301 /forums/topic/35332-formule-1-2017-op-pc-kijken-via-streams-zonder-ziggo/ /forums/topic/36172-formule-1-2018-kijken-via-live-streams-zonder-ziggo/
</IfModule>

I know this may be begging for trouble because the redirect solution is simple; however I ask, is it possible to change the topic ID provided you know both old and new IDs?

[Duken]

No i can't change the topic ID. How can i do this?

[PPlanet]

No, I wasn't suggesting it to you, sorry for hijacking your thread but today a mod on my site merged two threads the wrong way, just like you did.

I also applied the redirection solution (it's not the first time this happens to us), but in the back of my mind I was thinking that it would be nice if we could simply change the topic ID (via query or other way).

So, I'm also asking if it's possible at all.

Yup.

You, again, would need to get hacky with the database.....and I suggest you don't in this situation.

I suspected it wasn't a good idea. Thanks for the heads up anyway.
