    Microservices Engine:Migrate services from a built-in SAE or EDAS registry to an MSE Nacos registry

    Last Updated:Jul 17, 2026

    The MSE Sync migration tool synchronizes services registered in Serverless App Engine (SAE) or Enterprise Distributed Application Service (EDAS) to a Microservices Engine (MSE) Nacos registry with minimal configuration.

    Prerequisites

    Limits

    • If the MSE Sync tool goes down, synchronization is interrupted. We recommend that you deploy the tool on at least two nodes. Complete the migration as soon as possible after the process starts.

    • The SAE or EDAS built-in registry, MSE Sync, and MSE Nacos registry must be able to communicate over the network.

    Migration procedure

    Step 1: Obtain the SAE or EDAS namespace ID

    EDAS

    1. Log on to the EDAS console.

    2. In the navigation pane on the left, choose Resource Management > Microservices Space. In the top menu bar, select your target region.

    3. On the Microservices Space page, obtain the ID of the target microservices namespace.

      The ID is in the Microservices Namespace Name/ID column.

    SAE

    1. Log on to the SAE console.

    2. In the navigation pane on the left, choose Configuration Management > Distributed Configuration (ACM). In the top menu bar, select your target region.

    3. On the Distributed Configuration (ACM) page, click the Namespaces tab and copy the namespace ID.

    Step 2: Create a migration task

    1. In the left navigation pane of the MSE Sync tool, click Cluster configuration, and then click new cluster. In the new cluster dialog box, enter the AccessKey ID, AccessKey secret, namespace ID, and the region of your EDAS or SAE namespace from Step 1. Then, click OK.

    2. Click new cluster again to add the destination MSE Nacos cluster. For cluster type, select Nacos and enter the required information. If authentication is disabled for your MSE Nacos instance, leave the AccessKey ID, AccessKey secret, username, and password fields empty. Click OK.

    3. In the left navigation pane, click Sync Task, and then click New Sync. In the dialog box that appears, select the SAE/EDAS cluster that you created as the source cluster and the MSE Nacos cluster as the destination cluster. Select a synchronization mode and type. The services in the source namespace are automatically detected. Select the services to synchronize, and then click OK.

    4. View the synchronized service names on the Service Synchronization page.

    Step 3: Verify the synchronization result

    1. Log on to the MSE console, and select a region in the top navigation bar.

    2. In the left-side navigation pane, choose Microservices Registry > Instances.

    3. On the Instances page, click the name of the instance.

    4. In the left navigation pane, choose Service Management > Services to verify that the services are synchronized.
