Copy data from one data disk to another data disk ?

I am currently increasing the disk size of my data disk from 2 TB to 4 TB, I have done the increment in the Azure portal. As I am increasing my disk from the Disk management, the extend volume is greyed out. From what I am aware the disk is currently using MBR and the issue with MBR is that it only supports up to 2 TB. So I have added another disk of 4 TB made it GPT format, but copying data from one disk to another is a very hectic task the current disk is almost full. I cannot afford to lose the data from the disks. Is there any other way of copying the data from one disk to another without it taking so much time? (The copying might take more than a day)

    Hello @SHRADUL SAXENA ,
    Can you try using robocopy command .
    https://learn.microsoft.com/en-us/windows-server/administration/windows-commands/robocopy

    More significantly, that command has got an option /MT (Multi Threading) which will help out in copying the data of different folders in parallel.

    Please try out.

    You can also use multiple command windows to start the robocopy command for different folders

    Regards,
    Shiva.
