【问题描述】：
我正在尝试将 keycloak（以独立模式运行）从版本 8 升级到 12。我已按照提到的步骤 here
我删除了 data/tx-object-store/ 事务目录，并从版本 8 复制了独立目录。
我运行了升级脚本。我可以看到没有失败，所有步骤都是成功的。
我尝试用这个命令启动服务器
sudo ./standalone.sh -b 0.0.0.0 &
服务器启动成功，我可以访问 keycloak 管理控制台，也可以登录。我可以看到数据（用户、组等）也已成功迁移。
在这之后，我停止了keycloak
sudo ./jboss-cli.sh --connect command=:shutdown
运行良好。现在如果我尝试重新启动它，我会看到以下错误并且 keycloak 无法启动

我在内存数据库中使用 H2。我尝试安装 keycloak 12 并多次升级。每次我遇到同样的问题，第一次启动成功，然后就失败了。
有人可以帮忙吗？看起来当我第二次启动服务器时，它正在尝试再次迁移。但不确定。
【问题讨论】：
-
从 4.7 更新到 12 也无法正常工作，我们对版本 11 做了一个中间步骤，这似乎可以工作。
-
@ThomasBrüggemann 感谢您的反馈。我尝试从 8 升级到 11。我仍然遇到同样的错误。
-
我忘了我们需要解决这个 H2 错误：github.com/h2database/h2database/issues/1247（备份和恢复数据库）但不知道第 8 版 Keycloak 附带什么版本的 H2。
-
我设法通过逐步升级使其正常工作。 8-->9 9-->10 10-->11 11-->12
