hi!

For days I'm trying to export several spaces from one Confluence-account to another new account, using the data transfer possibility in the admin environment.  

In the process there is a validation step (step 4 of 5). Confluence tells me in this step, that every space needs an unique spacecode. 

But because it's a new environment, this can't be the case. Therefore, it seems impossible to import the spaces. Does anyone have any ideas on how to solve this?

thanks!

Marc

Hi @Marc de Vries,

Welcome to the Atlassian Community!

When importing spaces into a new Confluence environment, each space must have a unique identifier called a "space key." The space key is a short, unique code that distinguishes each space within your Confluence site.

Even though your new environment seems empty, it’s common for Confluence to create some default spaces automatically when a new site is set up. This can include personal spaces (for each user) or other default spaces, and one of these may have a space key that conflicts with the spaces you’re trying to import.

Here’s what I recommend:

  1. Go to your new Confluence environment and review the list of spaces that currently exist. You can do this by navigating to Confluence Settings > Security > Space permissions or use this direct link (replace <site-name> with your actual site name): https://<site-name>.atlassian.net/wiki/admin/permissions/space-permissions/allspaces
  2. If you find any spaces listed, delete them to ensure there are no conflicts with the space keys of the spaces you want to import.
  3. If you don’t see any spaces but still encounter this error, please open a support ticket with our team so we can investigate further and help you resolve the issue: https://support.atlassian.com/contact/#/

Let us know if you need any more help!

Best,

Matheus

Hi @Marc de Vries , welcome to the Atlassian Community and thanks for your post.

Yours is the third or fourth post I see about people having issues with the Confluence Data Transfer so I am flagging this post to Atlassian.

Somone will reply to you here (normally in 2-3 business days).

I have only selected one space that I know doesn't exist and the error is present. 
@Matheus Z you might want to look at this further.
