Chapter 2 Migrating from ACS 4.x to ACS 5.3

Overview of the Migration Process

Overview of the Migration Process

The Migration utility completes the data migration process in two phases:

•Analysis and Export

•Import

In the Analysis and Export phase, you identify the objects that you want to export into 5.3. The Migration utility analyses the objects, consolidates the data, and exports it.

After the Analysis and Export phase is complete, the Migration utility generates a report that lists any data compatibility errors, which you can manually resolve to successfully import these objects into 5.3.

The Analysis and Export phase is an iterative process that you can rerun many times to ensure that there are no errors in the data to be imported. After you complete the Analysis and Export phase, you can run the import phase to import data into ACS 5.3.

Migration Requirements

To run the Migration utility, you must deploy the following machines:

•The source ACS 4.x machine—This machine can either be an ACS 4.x solution engine or a ACS for Windows 4.x machine. The source machine must be running a migration-supported version of ACS. See Supported Migration Versions, page 2-2for more information.

•The migration machine—This machine must be a Windows platform that runs the same version of ACS (including the patch) as the source machine. The migration machine cannot be an ACS production machine or an ACS appliance machine. It has to be a Windows server running ACS for Windows. The migration machine requires 2 GB RAM.

•The target ACS 5.3 machine—Back up your ACS 5.3 configuration data and ensure that the migration interface is enabled on ACS 5.3 before you begin the import process. We recommend that you import data into a fresh ACS 5.3 database. To enable the migration interface, from the ACS CLI, enter:

acs config-web-interface migration enable

Supported Migration Versions

ACS 5.3 supports migration from the following ACS 4.x versions:

•ACS 4.1.1.24

•ACS 4.1.4

•ACS 4.2.0.124

•ACS 4.2.1
