svn项目迁移后服务器up报错：E155036 的处理方法

当项目开发迁移了SVN的地址后，进行svn up时服务器端报错

[1] refresh done, server ok. startTime: version:
svn: E155036: 请参阅命令 ‘svn upgrade’
svn: E155036: The working copy at ‘/home/xx/xx’
is too old (format 29) to work with client version ‘1.8.17 (r1770682)’ (expects format 31). You need to upgrade the working copy first.

解决方法：

1. svn upgrade [DIR_NAME]
