Removing Original Exchange 2010 server from Hybrid Environment

I have an Exchange 2010 hybrid environment. We use Office 365 for our mail now, but keep the hybrid environment as we manage users, etc on-premise and do some SMTP relaying against the hybrid server. I'm to the point where I want to remove the old Exchange server from the environment and have the hybrid Exchange server do all of the work. I have a link from MS that talks about how to do this. However, when I looked at the link in depth, it's really about removing the hybrid environment, which is NOT what I want to do.

Ultimately I want to remove the old original Exchange server and be left with the hybrid one that the consultant set up. Is this as simple as just removing an Exchange server from the environment where it's not the last Exchange server?  If so, does someone have a link to some good documentation on this?

It is recommended to have one exchange on onpremise to manage your users.
It is explained here

Right, I think that's the link that MS gave me. And basically what I'm trying to do is to leave the one Exchange server in place - which is the hybrid server that the consultant set up. The Hybrid server is running a full version of Exchange 2010. What I'm wondering... is removing the old exchange server in this hybrid environment the same process as removing one from an environment with just two on-premise exchange servers?  If so, is there a good document that outlines that process.

If you want to keep one server and remove the second server.
1. Do not remove any organization level configs.
2. Move mailboxes and system mailboxes to other server
3. Delete the database in the server to decommission.
4. Move public folder if any.
5. Uninstall Exchange server from Programs
Thanx...
