I am willing to clone the source space data into newly created space. As the proposed solution, using contentful CLI to export and import of the data, i am facing issue related to access.
And this is happening on partial data only, whereas partial data getting imported.
I am using the same user on CLI, having admin access for both export and import, where i am getting error access denies for partial records.
Refer the attached screenshot where total content types are 96 and only 48 got imported successfully and others failed with error.
This is resolved, this is the issue with the subscription that destination space holding. It has limited content types as compared to source space.
