So i've provisioned standard HDDs for the ASR storage and it turns out the churn is just over the ASR supported limits for that storage plan (just over 2Mb/sec)
The error in the portal says:
Learn how to upgrade https://aka.ms/upgrade-to-premium
Link doesnt work, and if i try to upgrade the disk through the portal its locked by the ASR and is in ActiveSAS state.
Is there a way i can upgrade this disk without deleting the whole site replication and starting again? its a good TB of data that i don't want to leave unprotected for the transfer duration.
