Switch WP-domain after signup with Multi-Domain installed

One of my members created his blog at name.domain1.com but now he/she wants to cange it to name.domain2.com. I’m using the Multi-Domains plugin and both domain1.com and domain2.com are selectable at signup. How do I make that switch, so that the main domain is changed, but not the subdomain/blog name?

I don’t want to ask my user to sign up a new blog since he/she has done alot of blogging on the current domain.

    Greetings Qlof,

    Thank you for this great question!

    Though I do not have an immediate answer myself, because the wrench in this is not change the sub domain name, I am at a loss.

    Therefore I will see if I can get the lead developer in here with his invaluable insight into this plugin for his advice/advise.

    Though this may take longer then a normal ticket, I will try to get him in here asap.

    Cheers, Joe

    Thanks for the response. That would be very appreciated.

    I assume it would be ok to make a search for the blogs domain and change it whereever it’s mentioned in the database. But I want to be sure as it’s a big blogsite and I can not mess up even if I make a backup :slight_smile:.

    It would be a great future for the admin to be able to change the blogdomain in the admin menu. So that’s a future feature suggestion :slight_smile:.

    Hey there.

    You could first try editing the domain here:


    Thats the site area of your Network Admin:

    Admin –> Network –> Sites

    If that didn’t fully change it all then you could edit the database directly and change all references from:




    Before attempting either of these please ensure you have full backups.

    Take care.
