Question about upgrade farm horizon 7 EOL to 2503

I should upgrade connection servers version 7.10 to the latest available released version. I have 4 connection servers, with obsolete and unsupported OS. I have proposed to carry out an upgrade involving the creation and replacement of 4 new vms with OS Windows Server 2022 and agent 2503. My doubt about the upgrade procedure is that I should add the 2503 connection server to the farm as a replica, elect it as master, and decommission the old Horizon 7 servers. Obviously the best, in my opinion, is to upgrade the OS and agent, but it is also the most time-consuming. is this procedure correct, or are there ‘safer’ procedures?
