There was a flag day for the transition from NCP to TCP/IP. There will never
be another flag day. Any transition solution, whether from IPv4 to IPv6 or a
successor protocol elsewhere on the stack, has to be designed to permit overlap
and interoperability during the very long period when both the old and new
protocols will be operating.
Further, there will have to be two incentives at work for the transition to
succeed. One is in favor of the the new protocol. The other is against the
old protocol. If the former is missing, the new protocol won’t be adopted. If
the latter is missing, the old protocol will persist indefinitely.
To repeat: there will never be another flag day. If this is one of your
assumptions, step back and think about the problem again.

this process until all technology companies prepare the updates and there

If a host still not updated, will not gain access to the Internet until
updating the OS.
