Full Database Export/Import

Question

I was attempting to export a full database from one server (DB files on the N: drive) and import it into a freshly created new database with the same instance name on a new server (DB files on the D: drive).
I was told to:
1) Export the full database as sys using full=y
2) Pre-create all of the tablespaces on the target database that do not exist on the target database
3) Import the full database as sys using full=y
=========================================================
Here are the steps I had to follow:
1) Export the full database as sys using full=y
2) Pre-create all of the tablespaces on the target database
3) Import the full database as sys using full=y - Result: over 1900 invalid objects and thousands of errors
4) Run Utlrp.sql - Result: 8 to 10 invalid objects
5) Manually attempt to compile or rebuild objects. Several grants were required to get most of these to work. - Result: After quite a bit of hand crafting, two objects are still invalid.
6) After spending almost two hours in a Collaborative Conference with an analyst who is working very hard to sold this, there are still two objects that are invalid.
Note: From my perspective this is not a straight forward process
=========================================================
Questions:
1) Has anyone successfully moved a database as described without all of these annoying steps?
2) Is there a document that details the full database export/import?
Thanks, RJZ

Hello RJZ,
There is not sufficient information to reply accurately to your queries,
1. Could you post the error message that you're getting when you compile these two programs? Do they compile okay on the old server?
2. What was the reason you choose exp and imp, to move your db to the new server and different disk? Were you migrating to a different version, or was it because of the db-reorg? It would have been possible to simple copy the db-files to the new location, and then rename the datafiles in mount-state. It would be more simpler I believe unless as stated above
Did you check the import logs? While importing were there any errors? Actually it should have been pretty straight forward (no reason why you need documentation for exp / imp). Grants should have automatically come, unless you have select grants=n option
I think because of the changes you have done for step-5, you might have changed some stuff somewhere. Please post the error message, and tell us if you have migrated the db to a higher version
