Is MySQL needed in Modernised ASR appliance approach

Joseline Monica 0

We are trying to protect onprem VMware environment using Azure Site Recovery using Modernised ASR appliance approach and enabled private networking for cache storage account and site recovery vault. Do we need to install MySQL in the appliance ?

Hello Joseline, in the modernized ASR appliance for VMware-to-Azure protection you do not need to install MySQL locally. MySQL is only a prerequisite for the classic Site Recovery “configuration server” approach (the old Azure Migrate/Classic ASR appliance). In the modernized architecture:

• All state and metadata are managed by Azure-hosted microservices

• There’s no embedded database requirement on the appliance VM

• You simply deploy the modern OVA, register it to your new (exclusive) Recovery Services vault, and go

If you’re seeing prompts or documentation about MySQL, double-check that you’re using the modernized ASR appliance OVA and following the “VMware disaster recovery – modernized” guidance rather than the classic “configuration server” flow.
