Simply export 8.17.0 datas to a new 11.8.0 server

hello, I’m new in gitlab managment. I have to migrate an old 8.17.0 gitlab server on a new 11.8.0 different server and I don’t know how to do that.

I’ve installed the new server which is empty.
I’ve tried to export a project but got an error when importing it :
Error importing repository - undefined method `import_jid’ for #ProjectImportState:0x00007f8e97ca0d78

Does anyone can give me some advice ?


I have a similar issue. I’m trying to import a project from a self-hosted 11.8.0 to current (11.8.0?).

After the uploading this error shows:

Error importing repository into project/name - undefined method 'import_jid' for #<ProjectImportState:0x00007f18d0147e28>
