Method 1 Create an ECS in the same region and AZ as the target server. Detach the system disk from the target server and attach the disk to the ECS. Search for and delete all antivirus software-related installation directories, registries, and startup items.
Public services, such as Elastic Cloud Server (ECS), Elastic Volume Service (EVS), Object Storage Service (OBS), Virtual Private Cloud (VPC), Elastic IP (EIP), and Image Management Service (IMS), are shared within the same region.
Log in to the ECS console, locate the target server, and detach the temporary system disk. For details, see Detaching an EVS Disk from a Running ECS. Log in to the API Explorer. Set the following parameters: Region: Select the target region.
If the EIP is frozen, contact ECS or EIP technical support. Check whether the required outbound ports are allowed in the security group of the source server. If there are no outbound rules for the protocols and ports shown in Figure 1, add rules for them.
Sign in to the ECS console. In the server list, locate this server and click its name. Click the Disks tab, locate disk SMS-Temp_Disk_Deleted-after-migration, and click Detach. Click Yes. Detach the original system disk. The original system disk is attached as a data disk.
Possible Causes Throughout the operations of the SMS-Agent, any interaction with Huawei Cloud services (such as EPS, IAM, and ECS) may trigger the SMS.6526 error. This occurs because Huawei Cloud performs account status validation.
Install the SMS Agent on each ECS to be migrated. For details, see How Do I Install the Agent on Source Servers? Run the SMS Agent and enter the AK/SK pair obtained in 1.
Step 3: Manually Add Extension NICs After the migration is complete, log in to the target server, an ECS, and manually add extension NICs. For details, see Attaching a Network Interface.
If the IAM users who will be added to this group need all SMS permissions, attach system-defined policies SMS FullAccess, OBS OperateAccess, ECS FullAccess, VPC FullAccess, and EVS FullAccess to the group. EVS KMSAccess must be attached if disk encryption is required.
Measurement Results During the network performance measurement, the system will check whether the source server can connect to the target server and related cloud services, such as IMS, ECS, EVS, and VPC, using their domain names In addition, it measures four core network metrics:
The IP address is used by ECS to access the metadata service. Using a Windows Agent Image (Python 3) Log in to the SMS console. In the navigation pane on the left, choose Agents.
a security group that opens the following inbound ports: Windows: ports 8899, 8900, and 22 Linux: port 22 for file-level migration, and ports 8900 and 22 for block-level migration CAUTION: For security purposes, you are advised to only allow traffic from the source server to the ECS
associated with the target server to allow traffic to these ports: Windows: TCP ports 8899, 8900, and 22 Linux: port 22 for file-level migration, and ports 8900 and 22 for block-level migration For security purposes, you are advised to only allow traffic from the source server to the ECS
Installing Huawei Cloud Password Reset Plug-in (Optional) To use the password reset function on the ECS console, you can install the Huawei Cloud password reset plug-in to reset the password with a few clicks.
associated with the target server to allow traffic to these ports: Windows: TCP ports 8899, 8900, and 22 Linux: port 22 for file-level migration, and ports 8900 and 22 for block-level migration For security purposes, you are advised to only allow traffic from the source server to the ECS
Available in all regions How Do I Select a Target ECS? Unlocking a Target Server During the migration, the target server is automatically locked to ensure successful migration. After the migration succeeds, the target server is automatically unlocked.
where T: the required migration time, in hours C: the total data volume of the source server, in GB S: the TCP speed (in Mbit/s) from the source server to the target ECS, that is, the TCP speed obtained in 4.b U: the network usage, which is related to network quality (jitter, delay
While an ECS supports up to 24 disks, SMS reserves one slot for a temporary disk during migration. This means that a source server can have a maximum of 23 disks. Disk size The mkfs tool included in the SMS agent image for Linux cannot create file systems larger than 16 TB.
If no existing server meets the requirements, click Create ECS and purchase an ECS with the required specifications. For details, see Purchasing an ECS. You can select a pay-per-use or yearly/monthly ECS.
