SonarQube 5.2升级到5.3时无法执行删除索引唯一模式迁移

我曾尝试在一个运行Windows 2008 R2 SP1的系统上进行升级，尝试多次后出现相同的错误。我们现在已经回滚到5.2。实际错误是：java.lang.IllegalStateException:无法在模式迁移上执行DROP INDEX unique_schema_迁移

以下是日志文件的一部分，以导致升级失败的错误结尾：

看起来5.2版本中缺少索引。要解决此问题，请在5.2数据库上为表架构_迁移创建索引。这是命令

在dbo.schema\u迁移（版本）上创建唯一聚集索引UNIQUE\u schema\u迁移

在此修复之后，我完成了从5.2到5.3的迁移
