我们的禅道，安装在Linux上后添加了插件，可能还进行了升级（升级历史我找不到了），现在显示是11.6版本。问题是，需要迁移到Windows。
为了要把它迁移到Windows环境，下载了11.6.4Windows版，在Windows安装后迁移了数据库表，并替换zentao目录为Linux上的zentao目录，登录时显示：

我看windows版php目录里有php7ts.dll，好像确实是PHP7，而查待迁移的Linux禅道里PHP是5.4版。于是下载旧版Windows禅道（10.6版）从中取php目录，替换windows里的php目录，结果禅道启动失败。
如何才能成功把它从Linux迁移到Windows？
谢谢！
