GEN4 Grid Replacement
As you are all aware, GEN4 Nodes are EOSL March 31, 2018. This means everyone has about a year to upgrade. This leads me to my question regarding GRID replacement.
We currently have a multi node GRID, and will be looking to replace it in the near future. The current options are to stand up a new grid, do a root-to-root. With the process, will there be down time? With a root-to-root, will you be able to rename the new grid the source grid's name once root-to-root has completed? I don't want to think about the process of re-registering all of my clients to another grid because of a different grid name. Has anyone completed a root-to-root from GEN4 to GEN4S or GEN4T? Please let me know if I am missing any options? Anything outside of the box I am missing? Downtime is going to be hard to come by, but It appears I have no choice?

A root-to-root migration to a new system normally ends with powering down the old system and renaming the new system to match the name of the old system. A brief downtime is required to execute the rename.
A root-to-root will be the fastest and easiest way to migrate to new hardware.

Thanks @Ian. I believe that answers my question. The Re-IP with same IP addresses for each node is also supported correct?

As long as the old system has been powered down or disconnected from the network, you can also change the IP addresses to match the old system, yes.
