Churn rate per disk

Question

I am using azure site recovery to protect on-prem VMs. I have a server with many replicated managed disks and some of the disks are going over limit churn causing the RPO to be out of date. Can we changed just the affected disks to premium or would all disks have to be changed to premium? Also, we would need to disable and re-replicate or can I just changed the disks property? Thank you.

Hello @Tyler Saville Thank you for posting your question on Microsoft Q&A platform. Happy to help!

I see that you have on-premises VM's protected using ASR and these VM's have high churn rate that conflicts with RPO and want to change the disks to premium. This is possible, you can easily change the type of managed disk for ongoing replications.

I don't think you need to disable and re-enable replication to change the disks as long as the new recovery points are generated.

Hope this answers your question. Please write back to us if you have any questions!
