Application Migration Service With Key Pair

Question

Hi All,

I used Application Migration Service to migrate one of our On-Premise VM machines to AWS Ec2, and I choose one of our existing key pairs on the template migration server.
After the Migration was completed successfully, I couldn't log in to the new AWS server through the Key pair but I can log in through username and password that the on-premise server setup with.
Is there a way to set up the key pair with the new server?

Answer

Application Migration Service MGN replicates the entire disk contents from onprem and even though you are asked to configure a launch template certain settings within the launch template have no effect. Keypair is one of them - See here for more details

Adding the keypair is possible only via a post launch script or via ssm agent. Your script would need to insert the public key into the ~/.ssh folder for the required user
