This table summarized support for the Azure VM OS disk, data disk, and temporary disk. It's important to observe the VM disk limits and targets for managed disks to avoid any performance issues.
Note
The target VM size should be equal to or larger than the source VM. The parameters used for validation are: Data Disks Count, NICs count, Available CPUs, Memory in GB. If it sn't a error is issued.
| Component | Support | Details |
|---|---|---|
| OS disk maximum size | 2048 GB | Learn more about VM disks. |
| Temporary disk | Not supported | The temporary disk is always excluded from the prepare process. Don't store any persistent data on the temporary disk. Learn more. |
| Data disk maximum size | 8192 GB for managed disks | |
| Data disk minimum size | 2 GB for managed disks | |
| Data disk maximum number | Up to 64, in accordance with support for a specific Azure VM size | Learn more about VM sizes. |
| Data disk change rate | Maximum of 10 MBps per disk for premium storage. Maximum of 2 MBps per disk for Standard storage. | If the average data change rate on the disk is continuously higher than the maximum, the preparation won't catch up. However, if the maximum is exceeded sporadically, preparation can catch up, but you might see slightly delayed recovery points. |
| Data disk (Standard storage account) | Not supported. | Change the storage type to managed disk, and then try moving the VM. |
| Data disk (Premium storage account) | Not supported | Change the storage type to managed disk, and then try moving the VM. |
| Managed disk (Standard) | Supported | |
| Managed disk (Premium) | Supported | |
| Standard SSD | Supported | |

| Boot diagnostics storage account | Not supported | Reenable it after moving the VM to the target region. |
| VMs with Azure disk encryption enabled | Supported | Learn more |
| VMs using server-side encryption with customer-managed key | Supported | Learn more |
The following table summarizes limits that based on our tests. These don't cover all possible application I/O combinations. Actual results vary based on your application I/O mix. There are two limits to consider, per disk data churn, and per VM data churn.
| Storage target | Average source disk I/O | Average source disk data churn | Total source disk data churn per day |
|---|---|---|---|
| Standard storage | 8 KB | 2 MB/s | 168 GB per disk |
| Premium P10 or P15 disk | 8 KB | 2 MB/s | 168 GB per disk |
| Premium P10 or P15 disk | 16 KB | 4 MB/s | 336 GB per disk |
| Premium P10 or P15 disk | 32 KB or greater | 8 MB/s | 672 GB per disk |
| Premium P20 or P30 or P40 or P50 disk | 8 KB | 5 MB/s | 421 GB per disk |
| Premium P20 or P30 or P40 or P50 disk | 16 KB or greater | 20 MB/s | 1684 GB per disk |
| Setting | Support | Details |
|---|---|---|
| NIC | Supported | Specify an existing resource in the target region, or create a new resource during the Prepare process. |
| Internal load balancer | Supported | Specify an existing resource in the target region, or create a new resource during the Prepare process. |
| Public load balancer | Supported | Specify an existing resource in the target region, or create a new resource during the Prepare process. |
| Public IP address | Supported | Specify an existing resource in the target region, or create a new resource during the Prepare process. The public IP address is region-specific, and won't be retained in the target region after the move. Keep this in mind when you modify networking settings (including load balancing rules) in the target location. |
| Network security group | Supported | Specify an existing resource in the target region, or create a new resource during the Prepare process. |
| Reserved (static) IP address | Supported | You can't currently configure this. The value defaults to the source value. If the NIC on the source VM has a static IP address, and the target subnet has the same IP address available, it's assigned to the target VM. If the target subnet doesn't have the same IP address available, the initiate move for the VM will fail. |
| Dynamic IP address | Supported | You can't currently configure this. The value defaults to the source value. If the NIC on the source has dynamic IP addressing, the NIC on the target VM is also dynamic by default. |
| IP configurations | Supported | You can't currently configure this. The value defaults to the source value. |
| VNET Peering | Not Retained | The VNET which is moved to the target region will not retain its VNET peering configuration present in the source region. To retain the peering, it needs to do be done again manually in the target region. |
Azure VMs that you want to move need outbound access.
If you're using a URL-based firewall proxy to control outbound connectivity, allow access to these URLs:
| Name | Azure public cloud | Details |
|---|---|---|
| Storage | *.blob.core.windows.net |
Allows data to be written from the VM to the cache storage account in the source region. |
| Microsoft Entra ID | login.microsoftonline.com |
Provides authorization and authentication to Site Recovery service URLs. |
| Replication | *.hypervrecoverymanager.windowsazure.com |
Allows the VM to communicate with the Site Recovery service. |
| Service Bus | *.servicebus.windows.net |
Allows the VM to write Site Recovery monitoring and diagnostics data. |
If you're using a network security group (NSG) rules to control outbound connectivity, create these service tag rules. Each rule should allow outbound access on HTTPS (443).
