I have been looking for options to migrate data present in my ADLS in one subscription to ADLS in another subscription within Azure. I tried ADF for this purpose and it worked fine.

But the copy speed is too slow in ADF. It copies at a speed of 10-15 KB/sec. Is there some way to increase speed of copy while using ADF?

Yes, there is a way you can migrate data from Azure Data Lake between different subscription: Data Factory.

No matter Data Lake Gen1 or Gen2, Data Factory all support them as the connector. Please ref these tutorials:

  1. Copy data to or from Azure Data Lake Storage Gen1 using Azure Data Factory.
  2. Copy and transform data in Azure Data Lake Storage Gen2 using Azure Data Factory.

You can create the source and sink dataset in different subscription through linked service: enter image description here

But this option may cost you some money. You also could ref the Azure Az-copy tutorials: Copy blobs between Azure storage accounts by using AzCopy.

Here is another blog How To Copy Files From One Azure Storage Account To Another:

  • In this post, Bloger will outline how to copy data from one Azure Storage Account in one subscription to another Storage Account in another subscription.

These maybe what you're looking for.
