I did a practice to migrate the oracle database from windows to linux operation system. The following is the operational process step by step. I recorded it in my blog for the future reference.

从10g开始，RMAN新增了CONVERT的语法，使得数据库文件可以跨版本复制，从这个特性开始，操作系统以及平台不再是数据库物理文件的限制了。

Oracle支持的可转换的平台可以在V$TRANSPORTABLE_PLATFORM视图中查询：

SQL> SELECT * FROM V$TRANSPORTABLE_PLATFORM;
