Oracle EXP Compatibility Matrix
Problem Description
From time to time we receive tickets that customers are having instantiation issues using legacy 'exp'.Oracle Support Note:Â Doc ID 132904.1Â has the entire matrix
Solution
Whenever you useÂ
expdp
 to export data, always use the same version Export Data Pump client as the version of the database from which you are taking dump. Although one major version lower of theÂexpdp
 client is allowed, it is not recommended. For example:If your database version is 11.1.0.6.0 then you can use theÂ
expdp
 tool from either 11g or 10g but it is recommended to use the 11.1.0.6.0Âexpdp
 tool.
Whenever you useÂ
impdp
 to import data always use the same version Import Data Pump client as the version of the database to which you are importing dump. Although one major version lower of theÂimpdp
 client is allowed, it is not recommended. For example:If your database version is 11.1.0.6.0 then you can useÂ
impdp
 tool from either 11g or 10g but it is recommended to use 11.1.0.6.0 theÂimpdp
 tool.
Import Data Pump (
impdp
) can always read Export Data Pump (expdp
) dumpfile sets created by older versions of the database. For example:Export dumpfile sets of database 10.1.0.5 can easily be imported into database version 11.1.0.6.
If you decide dumpfiles need to be imported into a lower version database then use theÂ
VERSION
 Export Data Pump parameter. Match the compatibility level of the database to the one which you will import. For example, to import dumpfile sets to a 10.2.0.1 database (where compatibility is set to 10.2.0.1) from an 11.1.0.6 database (where compatibility is set to 11.1.0.0):Append theÂ
VERSION
 parameter to the data pump export client command. For example, if the value ofÂVERSION
 needs to be 10.2, appendÂVERSION=10.2
 as a whole to yourÂexpdp
 command.
