Hi,
Possibly that there is post exists with same question, but I wanted to know what is the best way to create back up server? I want to place 2 servers in different locations and I have one server with 11.3 and second one with 11.4, so I want to update hardware on the first server and after use 2nd server for backup. Both servers in different locations. I looked at the forums and it is seems like parallel setup would work for me, but I can't find more information about that.
Thanks a lot.
