Hi,
We are trying to migrate from Oracle 7.3.4 to Oracle 8 using MIG80 utility.
Used MIG80 with the space check and created enough space for the system table space.

Later on running MIG80 resulted in the following error:

ORA-01562: failed to extend rollback segment number 0
ORA-01628: max # extents (2) reached for rollback segment SYSTEM

To solve this we increased the value of MAX_EXTENTS to 500 for the System Rollback segment. (Confirmed by the following select:
SELECT MAX_EXTENT FROM DBA_ROLLBACK_SEGS
WHERE SEGMENT_NAME = 'SYSTEM';

still it ended up with the same error. Please suggest a solution.

Thanks in advance,
Ratheesh
