Rolling upgrade

Currently we have two clusters running legacy mapr v1.  Unfortunately, these are kernel-less containers and so, they need to be re-installed.  The data will remain untouched and in tact.  As I plan on re-installing them, I also intend to upgrade to mapr v2, as it implements sgid support; something that is absolutely critical for us.

A couple of questions arise:
Can a mapr v1 cluster accept v2 nodes as members?

When it comes time to transition the cldb and zookeeper nodes, what is the best way of accomplishing this?
