When I tried to run this 1-5-6-ContentStoreMigration.zip
I got this.
Starting upload of patch.
Exception uploading patch: The MIME type of the uploaded file application/octet-stream was not accepted by the server.
Only files of type application/zip,application/x-zip-compressed can be uploaded.
Verify that you are uploading a file of the appropriate type.
I wonder if this is a Windows thing. I wouldn’t be surprised if most of us are using Mac/Linux. I’m not sure where the mime type comes from. What browser are you using?
