Change Domain Matrix/Element

[SebGG]

Hi,
i want to change my domain from one to another. What happens to the matrix/element apps when i change their location under the app settings.

Do the user names @user:matrix.domainOLD.de change to @user:matrix.domainNEW.de automatically?

Thanks in advance,
Sebastian

Good question! I’d love to know the answer to this. I don’t think that it would change the user’s matrix domain/id though. The first issue I can think of is encryption related and how that would cause the whole app/user/validation structure to fall apart.

@SebGG the apps won't work anymore if you change the location. The id will change but it loses track of previous IDs i.e all your federated contacts won't know about it. Maybe all the rooms local to the server continue to work. Generally, one should not change Domain Post Installation. This is not supported by matrix

If you really want to change domains, just make a new Matrix/Element instance, and then add the contacts, rejoin the rooms, etc, from the initial instance.

@SebGG yeah, there's currently no option to change a server name after it's set up (https://github.com/matrix-org/synapse/issues/3031 for reference)

@msbt right...

"Nothing has changed since 2018, it is still not possible to rename a server once it has done anything useful (eg sent a message, joined any room), please do not attempt to rename your server by manual database operations."
