Information in this document applies to any platform.


When attempting to migrate a P6 EPPM schema from Oracle Database to a SQL Server database, any unicode characters which are stored in an Oracle varchar2 datatype field will not migrate correctly to the associated SQL Server field causing a loss of all unicode symbols in the migration.  
For example, if a project ID (project.proj_short_name) contains Chinese characters in an Oracle Database, and the schema is migrated to SQL Server, all the unicode characters in the project.proj_short_name field will be lost.  

When migrating a P6 EPPM schema from Oracle Database which contains unicode characters in varchar2 datatype fields, to a SQL Server database, for the unicode characters to be retained in the migration.


  1. Create a P6 EPPM Oracle Database
  2. Connect to the database and change the project ID to Chinese characters
  3. Execute migrate.bat/.sh to move the Database from Oracle to SQL Server
  4. Connect to the migrated database and confirm the unicode characters are lost
