mimsoftware mim concurrent license server UPGRADE

Affected: >= 6.5.0 and <= 7.0.9

Fixed in: newer than 7.0.9

Safe to downgrade to: a release before 6.5.0

1. Check installed version

apt-cache policy mim-concurrent-license-server || rpm -q mim-concurrent-license-server || mim-concurrent-license-server --version

2. UPGRADE to newer than 7.0.9 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade mim-concurrent-license-server

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade mim-concurrent-license-server

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 6.5.0 (Debian / Ubuntu)

apt-cache madison mim-concurrent-license-server sudo apt install mim-concurrent-license-server=<VERSION_BEFORE_6.5.0> sudo apt-mark hold mim-concurrent-license-server

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

dnf --showduplicates list mim-concurrent-license-server sudo dnf downgrade mim-concurrent-license-server-<VERSION_BEFORE_6.5.0> sudo dnf versionlock add mim-concurrent-license-server

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.
