Create v4 server, keeping old v3 CA server until ALL manifests converted
We have a large num of systems, inc 2 masters and one ca server, all running v3.2.2.
What we'd like to do initially is to just create a v4 server & take advantage of the ability of v3 agents to talk to a v4 server.
ALSO, until the conversion of all the manifests etc is complete and we can finally replace the old masters, we'd like to continue using the current v3.2.2 CA master for all nodes, inc those nodes running updated manifests from the v4 server.
Is this possible? If so how, if not why not/best solns?
