Oracle 导入导出兼容性矩阵
是否有一个官方矩阵可以清楚地解释特定版本的导出转储格式如何与所有其他版本兼容或不兼容？
我的意思是填写这个网格：
Exp done with version: | 7 | 8i | 9i | 10g | 11g
Is compatible with Imp 7 |yes | no | no | no | no
8i|yes |yes | no | no | no
9i|yes |yes |yes | no | no
10g|yes |yes |yes | yes | no
11g|yes |yes |yes | yes | yes
我知道“是”和“否”之间有很多具体的想法。
我还需要Oracle官方这样明确的一句话： “Oracle 将始终支持向后兼容性以导入任何旧的导出转储格式”
请帮助我
Is there an official matrix that clearly explain how export dump format done with a specific version, is or not compatible with all others?
I mean to fill this grid:
Exp done with version: | 7 | 8i | 9i | 10g | 11g
Is compatible with Imp 7 |yes | no | no | no | no
8i|yes |yes | no | no | no
9i|yes |yes |yes | no | no
10g|yes |yes |yes | yes | no
11g|yes |yes |yes | yes | yes
I known there are many specific thinks between YES and NO.
I also need an Oracle official clear sentence like this:
"Oracle will allways support back-ward compatibility for import any old export dump format"
please help me

Metalink 132904.1 不同 Oracle 版本之间导出和导入的兼容性矩阵就是您正在寻找的文档。
我怀疑 Oracle 曾经承诺过永远支持某些东西。例如，11g 中不再支持常规导出命令，取而代之的是使用不同文件格式的 DataPump 版本。旧的导出实用程序将存在一段时间，但我不认为 Oracle 的 10 个版本甚至会发布非 DataPump 导出和导入实用程序的版本。
Metalink 132904.1 Compatibility Matrix for Export and Import Between Different Oracle Versions is the document you're looking for.
I doubt that Oracle has ever made a commitment that something will always be supported. For example, the regular export command is being desupported in 11g in favor of the DataPump version, which uses a different file format. The old export utility will be around for a while, but I wouldn't assume that 10 releases down the line Oracle would even be shipping versions of the non-DataPump export and import utilities.
