Copying an SSH key to the server even though you are already using SSH

I have already copied an SSH key to a server with ssh-copy-id -i ~/.ssh/skynet_key.pub.

Now I am building the gitlab-ci pipeline and have generated an new SSH key pair on my computer. I saved the private key as a variable in my gitlab project account.

Now I want to upload the new public key to the server.

My question is can I do this again from my local computer with ssh-copy-id?

Because I already have an SSH key pair distributed on both systems.

Would there be any problems here?
If so, how can I transfer the public key to the server?
Manually add the pubKey to authorized_keys?

As mentioned here, you can use the -o option (passed to SSH) to specify an existing key, in order to copy your second key:

ssh-copy-id -i ~/.ssh/<your-new-id-to-install> \
   -o 'IdentityFile ~/.ssh/<your-already-existing-id>' \
   <servername>`
