Centos 업그레이드의 극심한 위험 [닫기]

GLIBC_2.14를 사용하려면 CentoOS6.8을 7로 업그레이드해야 합니다. 내가 찾은이 링크여기에는 단계가 설명되어 있습니다.

7단계에서 해야 할 일은 다음과 같습니다.

centos-upgrade-tool-cli --network 7 --instrepo=http://mirror.centos.org/centos/7/os/x86_64/

다음과 같이 출력

preupgrade-assistant risk check found EXTREME risks for this upgrade.

Continuing with this upgrade is not recommended.

어떻게 해야 합니까? 강제로 하면 어떻게 되나요?
