Hi Jaeyub ,


A1: That would be one of the good choices but please note that the point release does matter. See the full list and details of OS that we support at 2019 R1 here

A2: This is an interesting question. I've never seen (or at least don't recall from long time ago) people doing it this way. My thought would be this 'should' be fine since your CentOS systems is totally unrelated to Ubuntu systems. Unfortunately, I can't guarantee but please feel free to try and let us know.


Thank you.
