backup and restore problem

[꾸꾸]

Moving from a Confluence cloud to a Confluence server.
space There was a problem while backing up and restoring.
1. I backed up and recovered Key name "kuk" space, but "kuk" and "op" were restored together.
2. I think. It seems to be recovered incorrectly. I am trying to delete confluence server's "kuk" and "op" space but it will not be deleted.
What can I do?
