If the source server is a Huawei Cloud ECS, follow the instructions in Resetting the Password for Logging In to an ECS on the Management Console. If the source server is not a Huawei Cloud ECS, find an appropriate method to reset the password.
In the security group of the ECS with Edge installed, add an inbound rule to allow access from the CIDR block of the elastic resource pool. Sign in to the ECS console. In the ECS list, click the name of the Linux ECS with Edge installed.
For the security group of the ECS with the MgC Agent installed, add an inbound rule to allow access from the CIDR block of the elastic resource pool. Sign in to the ECS console. In the ECS list, click the name of the Linux ECS with the MgC Agent installed.
