Safe to downgrade to: a release before 8.1

1. Check installed version

apt-cache policy edgeconnect-enterprise || rpm -q edgeconnect-enterprise || edgeconnect-enterprise --version

2. UPGRADE to 8.1.9.15 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade edgeconnect-enterprise

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade edgeconnect-enterprise

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 8.1 (Debian / Ubuntu)

apt-cache madison edgeconnect-enterprise sudo apt install edgeconnect-enterprise=<VERSION_BEFORE_8.1> sudo apt-mark hold edgeconnect-enterprise

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list edgeconnect-enterprise sudo dnf downgrade edgeconnect-enterprise-<VERSION_BEFORE_8.1> sudo dnf versionlock add edgeconnect-enterprise

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
