我正在努力升级虚拟机实例上的 gitlab omnibus 安装 (v12.3.0-ce)。我们的目标是最终升级到最新版本的 gitlab (v13.x)。根据文档我们需要先升级到 gitlab 版本 12.10.14，并且必须没有活动的背景迁移。
服务器升级后，我们执行以下命令重新配置系统sudo gitlab-ctl reconfigure。这个过程一直正常，直到 gitlab 版本 12.9.0-ce.0，此时 Sidekiq 会不断重新排队相同的后台迁移，并在其日志中产生以下错误：

这会阻止进一步的升级（所有后台迁移都必须成功执行）。有人对如何才能使迁移成功执行有什么建议吗？任何关于如何进一步解决此问题的建议也将不胜感激。
答案1
具体来说，运行升级后，执行 gitalb-ctl reconfigure，执行以下步骤：
sudo gitlab-rake db:migrate:status
并确保所有迁移都已启动。如果已启动，请运行以下两个命令：
sudo gitlab-rake db:migrate:redo VERSION=20200123155929
sudo gitlab-rake db:migrate:redo VERSION=20200127090233
