    Check out Oracle Data migration assistant. I think it is available with 8i Enterprise Edition.

    Here is something that I lately found out.

    Changing the character set of a Database in Oracle 8i

    It is possible in 8i to drectly change the character set of a database. This can only be done, however, if the new character set is a strict superset of the original character set. For instance, according to 8.1.6 documentation, the conversion can be made from the US7ASCII character set to three other character sets which are strict supersets:

    current New

    US7ASCII WE8ISO8859P1
    US7ASCII ALT24UTFFSS
    US7ASCII UTF8

    to change the character set from US7ASCII to UTF8, execute the following,

    SVRMGRL> startup mount
    SVRMGRL> alter system enable restricted session;
    SVRMGRL> alter system set job_queue_process=0;
    SVRMGRL> alter system set aq_tm_process=0
    SVRMGRL> alter database open;
    SVRMGRL> alter database character set UTF8;
    SVRMGRL> shutdown immediate; -- or normal
    SVRMGRL> startup

    In the cases where the new character set is not a strict superset of the original character set, a full export/import is necessary.

    I hope this can solve your problem :)

    Does it converts the current data or just the new ( inserted ) data.
    Thanks

    isn't it such thet after converting you must take care for string type columns (char, varchar2, ...) length:

    thier size is specified in bytes, if you convert to unicode (I believe Oracle use 2 bytes per Unicode char), then new data may not fit into old columns.
