Issue Plesk to Plesk Migration Not Working

[mdraselkhan]

Hello, I'm using AWS LightSail Instances for both servers. I tried to migrate from the old server to the new server. To do that I followed multiples guides. But at the end of the day, I failed to do. Suffering this issue for more than 2 months. When I try to get an error "Failed to connect to the source server 'source'by SSH: not a valid OPENSSH private key file".

The guides are that I followed:
1. Authentication by SSH (Linux)
2. How to set up SSH keys for Plesk server?
3. How to use SSH keys with Plesk
4. Resolved - Problem with migrating from Plesk ubuntu to Plesk ubuntu

I think I did something that related to the server users, which user account should I use to do?

The old server has [ubuntu & root] users.
And the new server has [centos & root] users.

Anybody here to guide me step by step?

So many thanks in advance.

Resolved - Problem with migrating from Plesk ubuntu to Plesk ubuntu

I am using ecc2 instances for Plesk and want to migrate customers from one Plesk server to to another but the keys are not able to be authorized. By default you don't have private keys stored in an ec2 instance and public keys are stored in /root/.ssh/authorized_keys and tried the public keys...

@IgorG
Thanks for your reply.
I was run the ssh command [$ ssh-keygen] as a "root" user not a "centos" user on the new server (targeted). Then I copied the text from the /root/.ssh/id_rsa.pub file of the new server (targeted) to the old server's (source) /root/.ssh/authorized_keys file. Here is I removed all existing text from the old server's (source) /root/.ssh/authorized_keys file, then I paste the copied text. After that, I restart the ssh service by the command [$ service sshd reload]
