Change from Standard HDD to Premium SSD after ASR setup

I have a VM that is very large now fully replicated to Azure using Azure Sit Recovery. When testing DR, I was unpleased with the performance and noticed that the ASR configuration is using HDD for the disk destination. I would like to change this to Premium SSD. Is there any way to do this without starting completely over and replicating the entire machine again?

    Hello @AdamTyler-3590 Thank you for posting your question on the Microsoft Q&A platform. Happy to answer any questions you may have!

    Based on the information shared, I understand that you want to change the disk type from Standard HDD to Premium SSD without building it from scratch and replicating the machine again.

    Yes, it is possible to change the disk type. Ref doc: https://learn.microsoft.com/en-us/azure/site-recovery/vmware-azure-common-questions#can-i-change-the-managed-disk-type-after-a-machine-is-protected

    In case of Azure-to-Azure replication, following steps applies:

    1. Go to Disks of the affected replicated machine and copy the replica disk name.
    2. Go to this replica of the managed disk.
    3. You might see a banner in Overview that says an SAS URL has been generated. Select this banner and cancel the export. Ignore this step if you don't see the banner.
    4. As soon as the SAS URL is revoked, go to Configuration for the managed disk. Increase the size so that Site Recovery supports the observed churn rate on the source disk.

    Hi Adam,

    In ASR you can change VM size but not disk. So the way will be failover the VM with HDD and then change it to Premium SSD. You can follow below steps and it's also fast and easy:
