We need to migrate database from one server to new server using same database version 11g Release 2 (18.104.22.168.0). We have some production objects in sys schema. We took full export using full=y and then import on new server using full=y. Other objects belonging to different tablespaces and users has successfully imported but production objects i.e table in sys schema not import.
We used following commands for export and import:
# exp system file=/u01/backup/orcl_full_exp.dmp log=/u01/backup/orcl_full_exp.log full=y statistics=none
# imp system file=/u01/backup/orcl_full_exp.dmp log=/u01/backup/orcl_full_imp.log full=y ignore=y
First of all it is not good practice to keep user object in the sys schema
second you are useing version 11gr2 what not you go for datapump export/import method.
third, did you get any error in import, what is the error
