To upgrade openSUSE Leap to a newer release, use the openSUSE migration tool when your current and target releases are on its supported path. For example, openSUSE’s guidance for moving from Leap 15.6 to Leap 16.0 recommends this tool. It updates the distribution repositories, checks the system, and runs the package distribution upgrade. Tumbleweed is different: it is a rolling release, so you update to a newer snapshot with zypper dup instead of migrating to a numbered Leap release.
Check the installed edition and version first:
cat /etc/os-releaseIf the output identifies Leap, read the target release notes and the project’s system upgrade guidance. The official migration-tool guide covers Leap 15.6 to Leap 16.0; check the supported route for other starting versions. Review the release notes for your target, and use a stable release rather than a release-candidate image on production systems.
For Leap 16.0, the migration tool checks whether the machine meets the x86-64-v2 CPU requirement. If the check reports incompatible hardware, stop and choose a supported release or system; do not try to bypass the check.
Copy your personal files and important system configuration to storage outside the machine. Include /home, files under /etc, application data, and database backups where relevant. Verify that the backup can be read. A Btrfs/Snapper snapshot can provide a quick rollback option when configured, but it is not a substitute for a separate backup.
Check free space with df -h, especially on the root filesystem, because the upgrade needs room for package downloads and installation. Apply pending updates to the current Leap release first:
sudo zypper patch
On a server, schedule downtime, stop virtual machines, and back up databases with their normal tools. Arrange console access for a remote system, then keep power and internet available throughout the migration.
sudo zypper in opensuse-migration-tool
If it is unavailable on an older Leap system, follow the source-specific steps on the official system-upgrade page.
/usr/sbin/opensuse-migration-tool --dry-run
Resolve hardware or readiness issues first, and check the release notes for changes affecting your desktop, services, drivers, or applications.
sudo opensuse-migration-tool
Choose the supported stable Leap target. The tool recommends disabling non-distribution repositories because third-party packages may not support the new release yet. Re-enable a source only after its maintainer confirms compatibility.
sudo reboot.
After signing in, verify the version with cat /etc/os-release, then check networking, graphics, applications, and services. Re-enable third-party repositories only after their providers confirm support. If the system will not boot, a previous Snapper snapshot may be available from the boot menu if snapshots were configured.
Tumbleweed receives rolling snapshots rather than numbered Leap releases. To update it, use the distribution-upgrade command:
sudo zypper dupReview the proposed package changes and answer Zypper’s prompts. Do not substitute zypper up for the full Tumbleweed update procedure. See the official Tumbleweed updating and rollback guide for current details.
Conflicts often come from repositories built for the old release. Disable sources that do not support the target and follow official instructions to refresh its repositories; do not force zypper dup across mismatched sources. If the tool reports incompatible hardware or no direct upgrade path, stop and use source-specific instructions or plan a clean installation after backing up. Installer flows change between major Leap releases, so old USB and boot-menu steps are not universal.
For current images and release information, use the official openSUSE Leap download page and the corresponding release documentation.
