Moving files from ADLS to Unity Catalog External Volume

[NC]

Hi All,

I am trying to migrate files from ADLS to newly created UC External Volume. 

I tried using dbutils.fs.cp but failed.

May I know what is the right way to copy files without any transformation from ADLS to UC external volume.

Thank you

You don't need to move / copy data at all. Just link the new volume to the existing storage location.

The problem here is, the old ADLS storage will be dismantled after we move to Unity Catalog.

Solve this in Azure, by using e.g. az copy / Storage Explorer to move the data to new location. The volume should use this new location.

Instead of copying your files from ADLS to UC volumes, you can create a storage credential and an external location. This allows you to access all your ADLS data directly through the catalog explorer under external locations.
