Which servers might you consider retiring after activating an SSH server?

After activating an SSH server, you might consider retiring any legacy servers that are no longer receiving updates or support, as they can pose security risks. Additionally, servers that provide redundant or overlapping functionalities with the new SSH server could be candidates for retirement. It's also wise to evaluate servers that have low usage or are rarely accessed, as they may not justify the maintenance costs. Finally, any servers that do not meet current security standards should be considered for decommissioning.
