VC fw를 downgrade 시도 시 아래와 같은 오류가 발생하는 경우,
ERROR: Internal Error: Downgrade from this version of Virtual Connect firmware to the target version is not supported and would result in destruction of the domain. Manually delete the Virtual Connect domain and run the Virtual Connect Support Utility again.
현재 사용 중인 VC fw에 구현된 기능이 downgrade 하려고 하는 target fw 버전에서 구현되지 않은 기능을 포함하고 있을 때, 현재 사용중인 VC fw에서 VC Domain이 구성되어 있는 경우다.
- VC Domain을 유지한 상태로 Downgrade는 업그레이드 직전 버전 한 가지로만 가능하다.
예를 들어, 3.75를 사용하다가 4.21을 적용 후 4.50을 적용했다면, 내려갈 수 있는 버전은 4.21 한 개 버전임
- vcfw 3.17 이하로는 내릴 수 없다.
Action Plan.
What: VC Domain 삭제 후 대상 하위 VC fw 적용
To do.
1) 모든 서버의 전원 종료(Downgrade를 위해 필수)
2) VC 구성 백업 후 삭제
(필요한 경우 구성 정보 백업하고, 구성한 도메인이 없는 경우 임의로 도메인을 생성한 후 삭제)
a) VCM > Tools > Backup Domain Configuration > Save
b) VCM > Configure > Domain Settings > Delete Domain
3) vcsu 통해 다운그레이드 수행
vcsu -a update -i <% OA IP Address %> -u Administrator -p Password -l C:\vc\vcfw.bin -f version,health -vcu Administrator -vcp Password
e.g.) OA and VC Credential
Administrator / Password
