Can one export a schema from a 64 bit Oracle DB into a 32 bit Oracle DB?

Question

Hello:
I need to copy a schema from one DB to another. The source DB runs 64 bit version of Oracle DB but the target DB runs 32 bit version of Oracle DB. Can the schema in 64 bit DB instance be exported and imported into a 32 bit DB instance with exp/imp or expdp/impdp command? Thanks.

Hello:
Thanks for your help. Please see part of the error message below. In the new db, I have created the same user with same password and also grant connect and resource privilege to that user. But I don't understand why some table could be recreated without any issue while all those with BLOB column cannot.
