ibm app connect enterprise UPGRADE

Affected: >= 12.0.1.0 and < 12.0.12.28 · >= 13.0.1.0 and < 13.0.8.2

Fixed in: 12.0.12.28, 13.0.8.2

Safe to downgrade to: a release before 12.0.1.0

1. Check installed version

apt-cache policy app-connect-enterprise || rpm -q app-connect-enterprise || app-connect-enterprise --version

sudo apt update && sudo apt install --only-upgrade app-connect-enterprise

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade app-connect-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 12.0.1.0 (Debian / Ubuntu)

apt-cache madison app-connect-enterprise sudo apt install app-connect-enterprise=<VERSION_BEFORE_12.0.1.0> sudo apt-mark hold app-connect-enterprise

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

dnf --showduplicates list app-connect-enterprise sudo dnf downgrade app-connect-enterprise-<VERSION_BEFORE_12.0.1.0> sudo dnf versionlock add app-connect-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.
