bloomreach experience manager UPGRADE

Affected: >= 14.1.0 and <= 14.2.2

Fixed in: newer than 14.2.2

Safe to downgrade to: a release before 14.1.0

1. Check installed version

apt-cache policy experience-manager || rpm -q experience-manager || experience-manager --version

2. UPGRADE to newer than 14.2.2 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade experience-manager

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 14.1.0 (Debian / Ubuntu)

apt-cache madison experience-manager sudo apt install experience-manager=<VERSION_BEFORE_14.1.0> sudo apt-mark hold experience-manager

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

dnf --showduplicates list experience-manager sudo dnf downgrade experience-manager-<VERSION_BEFORE_14.1.0> sudo dnf versionlock add experience-manager

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.
