为什么从TFS 2010升级到TFS 2015的TFS升级到“验证数据库连接字符串是有效还是可修复”？

Question

我有一个远程SQL Server 2012 SP1实例，我已在该服务器上恢复了TFS数据库Tfs_Configuration，TfsWarehouse和Tfs_MyCollection。这些数据库来自TFS 2010 / SQL Server 2008应用程序/数据层的备份。

我的新应用程序层服务器是TFS 2015 Update 4 / Windows 2012 R2的全新安装。我使用TFS配置中心升级向导配置我的TFS 2015实例以使用从TFS 2010 / SQL Server 2008组合中还原的远程SQL Server数据库。

不幸的是，准备检查在“验证数据库连接字符串是有效还是可修复”时挂起并且没有进展。

为什么会这样？根据我所遵循的文件https://docs.microsoft.com/en-us/vsts/tfs-server/upgrade/tfs-2005-to-2015

，这个过程看起来非常简单

*注意：我无法运行TFSConfig RemapDB，因为2015服务器没有DB开头。

Answer 1

从错误消息中，您的Tfs_Configuration数据库似乎有问题。请尝试从旧TFS 2010备份此数据库，然后在新服务器上再次恢复（如果有）。

Configure my TFS 2015 instance to use the remote SQL Server databases that were restored from the TFS 2010/SQL Server 2008 combo.根据您的描述，SQL2012和SQL2008安装在一台服务器上，同时确保在使用TFS升级向导时卸载SQL2008 Server，否则可能会导致某些问题或冲突。

而且你直接安装了TFS2015 update4。建议您首先安装TFS2015 RTM版本并进行升级，在TFS升级后配置功能，最后将TFS2015更新为TFS2015 update4。见TFS support for SQL Server
