      This document provides a sample configuration for the scenario that both the VPC and classic network are required during the business migration.

      Scenario

      Resource configuration of the classic network-based business:
      The CVM client accesses a private network CLB.
      The private network CLB is bound with two CVMs (CVM 1 and CVM 2) as the real servers.
      Applications deployed in CVM 1 and CVM 2 can access the backend TencentDB for MySQL services.
      Requests:
      Migrates resources from the classic network to a VPC
      The VPC-based clients has a priority access to the private network CLB service in the classic network.
      The classic network access remains available for one month after the migration.

      Migration process

      1. Create a VPC
      2. Migrate TencentDB services
      3. Configure a terminal connection
      4. Create a private network CLB and configure its backend service
      5. Configure a Classiclink
      6. Release the classic network resources

      Steps

      1. Create a VPC as instructed in Creating VPCs.
      2. Migrate the TencentDB for MySQL services to the VPC as instructed in Network Switch.
      Note:
      During the migration, the TencentDB instance still connects. Both the original classic network IP and VPC IP addresses remain valid after the migration, thus maintaining your service availability.
      3. Configure a terminal connection service to allow the CVM client in the VPC to access the public network CLB service in the classic network.
      Note:
      A terminal connection does not support cross-region or cross-account communication. If you want to establish a terminal connection, please submit a ticket.
      4. Create a private network CLB instance and its real server in the VPC, and configure the related services.
      5. Configure a Classiclink to allow the classic network-based CVM to access the private network CLB instance in the VPC. Test whether the VPC provides services normally.
      6. After the VPC service is normal and VPC-based CVM starts accessing the private network CLB in the VPC, delete the terminal connection, maintain Classiclink, and release the resources in the classic network.
