Sorry if this has been answered before. I might want to transition to managed ssd from my current managed vps - how much downtime would I experience and would IP's, access to cpanel, FTP, etc. change?
Typically; they'd wouldn't receive a message at all -- it would be delivered to the old host/server that you were migrating away from.There's one thing I would like to clarify. If let's say there's a downtime of 10-15 minutes during my migration to VPS SSD, and that I use private nameservers (ns1.mydomain.com, ns2.mydomain.com), what will happen if someone sent me an email coincidentally during that downtime (e.g. using their Gmail, Yahoo, Hotmail account), will they immediately receive "No MX or A records for mydomain.com" hard bounce type of error?
