Error trying to overwrite page blob with block blob in place. #111

Closed StandBackBurrito closed 4 years ago

StandBackBurrito commented 4 years ago

I am trying to convert some page blobs to block blobs without creating new blobs.

In my case the source and destination container (and blob for that matter) are the same.

The source blob is a page blob my expected outcome is that it is overwritten as a block blob

I get the same error when I attempt to copy a block blob from one container to another if a page blob with the same name already exists. If I delete the page blob I am then able to copy the block blob to the container.

 .\blobporter -f "https://mysourceaccount.blob.core.windows.net/container/myblob" -c container -t blob-blockblob

The Azure Storage API does not support overwriting an existing blob with a blob of a different type.
