change folder heirarchy in a tar file without extracting to disk

[Jerome Yanga]

Is there a way to change the folder structure inside a tar file without extracting it to disk first?

For example, I have the following file/folder structure in a tar file, test.tar.

dir1/
dir1/file1
dir1/file2

I would like the contents to be modified to.

dir2/dir1/
dir2/dir1/file1
dir2/dir1/file2

Thank you in advance.
