Thanks for the replies..I tried every option suggested by IBM

1. Set DB2CODEPAGE=1208 and use db2move export & import (or load)
Problems: Data got truncated in most of the tables during export. This casued constraint violations during the import. Lobs & data in some coulumns also got truncated
2. without db2codepage reg variable, use db2move export & then use iconv to convert the data..this also gave the same problems during import
luckily , the application is still in development ..so we are thinking to cleanup the portal & re-install it
