A few weeks ago I have done similar migration;

source: Oracle database worked on SunSolaris 8

destination: oracle database worked on Intel x86_64


I you have small database f.e less than 200GB consider to use EXP/IMP Oracle programs (included on each Oracle Database server: see exp help=y as database owner with ORACLE_HOME environment)

In this option remeber that you need an appropriate undo tablespace and undo retention ( if it is used) or rollabck segmets configured on source database


If you database is larger than 200-300GB consider to upgrade database.



first step: upgrade to

second step: upgrade to


In both situation application/users could not to connect to database during migration process
