Hello,
I am trying to migrate a space/project from one instance to another (ex. name1.atlassian.net to name2.atlassian.net) by using the Data Transfer tool. When validating the data I get an error that there is already a space that exists in the destination with the same key (ex. SP).
I checked the destination instance and there are no projects with SP that are active, archived, or in the trash.
Secondly, when I try to change the key of the space I'm migrating (from SP to SPU) to work around the error, the changed key is not getting properly reflected in the Data Transfer page (it still shows the old key SP, not SPU).
