升级的好处 我就不多说了，这里介绍一点升级过程中的tips。
比较文件
将程序解压、解包之后放入与上一版本同级的目录，取名mt3.34
./mt
./mt3.34
上一版本因为额外安装有插件以及个别hack文件，不能完整替换，先比较两个目录，使用-q 参数忽略具体文件差异，-r 递归子目录。
$ diff -qyr mt3.34 mt |grep Only
Only in mt: mt-config.cgi
Only in mt3.34: mt-config.cgi-original
Only in mt/php/extlib/smarty: .cvsignore
Only in mt/php/plugins: block.MTBlogrollCategories.php

合并文件
然后将上一版本多出或者更新日期更新的文件copy 到新版本，为了保险起见，使用-i 参数确认任何文件覆盖。
$ cp -iur mt/plugins/* mt3.34/plugins
然后手动编辑合并曾经hack 过的文件，在这里我曾经修改了mysql.pm 以及批量编辑basename 所需的相关文件。
$ diff mt3.34/lib/MT/ObjectDriver/DBI/mysql.pm mt/lib/MT/ObjectDriver/DBI/mysql.pm
1c1

> $driver->{dbh}->do("SET NAMES " . $c) or
99a100
> $driver->{dbh}->do("SET NAMES 'utf8'");
可以使用vi 同时编辑多个文件，使用:n 与:N 命令进行切换，剪贴板缓冲区是共享的，方便copy 代码行。
$ vi mt3.34/lib/MT/ObjectDriver/DBI/mysql.pm mt/lib/MT/ObjectDriver/DBI/mysql.pm
批量编辑basename 一般在大规模迁移时才会用到，这次就不修改了。
cgi-bin 目录的所有升级就完成了，把mt-statics copy 到相应目录，重复以上步骤。
版本切换
全部完成后，把两组新旧目录名称迅速交换，再打开MT控制台，发现升级已经生效，没遇到任何错误，算是无缝切换。
