We have an unmanaged VPS and need to do a software upgrade to a newer protocol of SparkPost so the API calls are not rejected for our HTTP, FTP, email, and webmail.
I am very experienced in systems deployment and maintenance. My proposal is to clone your system, perform the upgrade and deploy when functional. Documentation will be delivered.
