I have migrated about 6 DB's from 8i to 11g and yes, the sys tablespace have different contents (some views, packages and sp's have changed or disappeared), don't forget that 11g is case sensitive for example (you would like disable that function probably).

Personally, I created the tablespaces on the new db, then created the objects (generated the DDL of all tables, indexes, triggers, sequences, sp's and packages) and then just made an export file with the contents of the tables only, fast and "easy", I have used this method on all the db's without any problem.

Before decide any option, I tried different methods (importing datafiles from 8i to 11g, direct upgade, migration to 10g and then upgrade to 11g, a single full export file, copy of objects directly without db's, a 10g db in the middle), some of them "worked", but the list of errors were huge or critical so that the process would be highly risky or I would have spent more time finding and fixing all the errors than copying the objects one by one.

That's from 8i of course...
