What's going on when gitlab can't be upgraded?

Friends who use GitLab recently found that upgrading the GitLab version has become a troublesome thing. Before upgrading, there are some necessary things to note to ensure that the upgrade is successful and no data is lost.

1. Back up data

Before upgrading, be sure to back up all data in GitLab, including databases, repositories, configuration files, etc. This is a necessary step to prevent data loss and upgrade failures. It is recommended to use the backup command that comes with GitLab for backup. For specific operations, please refer to the official documentation: https://docs.gitlab.com/ee/raketasks/backup_restore.html#creating-a-backup-of-gitlab.

2. Check the update log

Before deciding to upgrade the version of GitLab, you need to check the update log of GitLab to learn about the problems fixed and new features of the new version. At the same time, you also need to check GitLab's update documentation to learn what you need to pay attention to and the specific operation methods during the new version upgrade process. These can help us better prepare for the upgrade.

3. Check the system environment

In addition to GitLab's own environment settings, you also need to check whether the system environment meets the requirements of the new version. For example, whether the required dependencies are installed, whether there is enough disk space, whether the system memory is sufficient, etc. If the system environment does not meet the requirements, upgrading GitLab may fail or cause the system to crash.

4. Minor version upgrade

If the GitLab version to be upgraded is significantly different from the current version, it is recommended to perform a minor version upgrade first and gradually upgrade to the target version. For example, if the current GitLab version is 11.0 and you want to upgrade to 13.0, you need to first upgrade to 11.1, 11.2, 11.3 and other gradual upgrade versions before finally upgrading to 13.0.

5. Stop the service

When upgrading GitLab, make sure that the GitLab service has been stopped. Otherwise, problems such as file locking may occur during the upgrade process, causing the upgrade to fail. You can use the GitLab built-in command to stop the GitLab service. For details, please refer to the official documentation: https://docs.gitlab.com/ee/administration/restart_gitlab.html#stop-gitlab.

6. Perform upgrade

If there are no problems with the previous steps, we can perform the upgrade operation. The upgrade command can be executed through the command that comes with GitLab. For specific operations, please refer to GitLab's official documentation: https://docs.gitlab.com/ee/update/#update-gitlab-ce.

7. Check whether the upgrade is successful

After the upgrade is completed, you need to restart the GitLab service and log in to GitLab using an administrator account to check whether the upgrade is successful. If something goes wrong, you can find the problem by looking at the GitLab log files.

To sum up, upgrading GitLab requires certain technical requirements and experience, and we need to make sufficient preparations before operation to ensure a successful upgrade. If you encounter problems, you can go to GitLab's official forum for consultation, or submit an issue for help.
