소프트웨어는 항상 버그가 있고 성능개선이 있어 업그레이드가 꼭 필요하다.
Greenplum 도 6.10.x. 이하 버전에서 확인된 버그가 발견되어 6.11.0 이상으로 업그레이드를 권장하고 있다.
그래서 Greenplum 6.3.0 에서 6.11.1 로 업그레이드를 해보도록 하자.
## 업그레이드시 유의사항
-
Greenplum DB의 downtime 이 발생한다. (어플리케이션, ETL 프로그램등을 잠시 중단하여야 한다.)

## 업그레이드 시작
1. 설치파일 다운로드
network.pivotal.io/products/pivotal-gpdb#/releases/743424
Download VMware Tanzu™ Greenplum® — VMware Tanzu Network
Explore, download, and update software and services.
network.pivotal.io
URL로 접속한뒤 Greenplum Database Server 를 선택 > OS에 맞는 파일을 선택하여 다운로드한다.
Greenplum 다운로드를 할려면 Tanzu 계정이 필요하다. (Greenplum 을 계속 공부하려면 계정생성을 권장한다.)
!! Greenplum은 오픈소스이나 vmware tanzu Greenplum 은 다른제품이라고 할 수 있다. !!!
추후 오픈소스 Greenplum과 tanzu Greenplum 의 차이점을 포스팅해봐야 겠다.
현재 설치되어 있는 OS가 RedHat 7.x 이라 for REHL 7을 선택하여 파일을 다운로드한다.
2. 다운로드한 Greenplum 6.11.1 설치파일을 master 노드에 업로드(나는 /root/ 폴더에 업로드)
