Re: "Old generation AWS instance is configured for remote site AWS"
Just as a followup to this, it seems that the aws machine generations are designated by the number following 'm'.
So m1, m2 etc. For whatever reason configuring the remote site provisioned an older generation instance. I'm in contact with Dell/Nutanix support to update the instance type, I'll try to remember to post back if it was successful and if existing data was preserved.
