Migrating DB2 v8.2 to 9.5

Hi all,
I am using a sms managed dbs which to be migrated to 10.1 for 32 bi. One i have migrated successfully. By taking full offline backup which is done usually in circular database. I restored that backup taken on v8 to 9.5. succeeded. Again took backup of 9.5 for 10.1. And finally restored successfully. upgraded successfully message got.
same procedure i am doing with other two databases. it fails. what i am missing. second it gave error sql2519 "1224" return "N" like that. any clue.

thanks
