However, if a consistent snapshot of the database is required (for data integrity or other purposes), then the database must run in restricted mode or must otherwise be protected from changes during the export procedure.

The Export/Import data migration method does not change the current database, which enables the database to remain available throughout the upgrade process. If you are upgrading from 10.2.0.2, 10.2.0.3, 10.2.0.4, or 10.1.0.5, then you must first upgrade to 10.2.0.5 or later.ДЇor release 9.2.0.8, you must first upgrade to an intermediate Oracle Database release, as follows:Дў.1.3.3.1 The Effects of Export/Import on Upgraded Oracle Databases If you are upgrading from 11.2.0.1 or 11.1.0.6, then you must first upgrade to Oracle Database 11g Release 2 (11.2.0.2). Then, upgrade the intermediate release database to the new Oracle Database 12 c release using the instructions in Chapter 3, 'Upgrading Oracle Database'. When upgrading to an intermediate Oracle Database release, follow the instructions in the intermediate release's documentation. This does not include upgrading using Oracle Data Pump export/import. Solution: Upgrade to an intermediate Oracle Database release (that can be directly upgraded to release 12.1) before you can upgrade to the new Oracle Database 12 c. Perform the upgrade using the current Oracle Database Upgrade Guide, which is this guide.Дirect upgrade to Oracle Database 12 c is not supported. Then the Direct or Intermediate Upgrade Path is:Дirect upgrade is supported. Table 2-1 Examples of Upgrade Paths for Oracle Database 12 c If your Current Release is: Use the upgrade path and the specified documentation to perform an intermediate upgrade of your database before fully upgrading to Oracle Database 12 c. Table 2-1 contains the required upgrade path for each release of Oracle Database. Upgrade Oracle Database 10 g Release 2 (10.2.0.5) directly to the new release of Oracle Database 12 c using the instructions in Oracle Database Upgrade Guide, which is this book. Upgrade release 9.0.1.4 to release 10.2.0.5 using the instructions in Oracle Database Upgrade Guide 10g Release 2 (10.2). In this case, you are required to upgrade to an intermediate release before upgrading to Oracle Database 12 c.ДЇor example, if the database from which you are upgrading is running Oracle Database 9 i, then follow these steps: If your current Oracle Database is a release earlier than 10.2.0.5, or is release 11.2.0.1, then directly upgrading your current release of Oracle Database to the latest release is not supported. You may directly upgrade from release 12.1.0.1 to 12.1.0.2. You may perform a direct upgrade to the new release if your current Oracle Database is release 10.2.0.5, 11.1.0.7, or release 11.2.0.2 or later. The path that you must take to upgrade to the latest release of Oracle Database 12 c depends on the release number of your current database. 2.1.2 Determine the Upgrade Path for Oracle Database
