Migration Guide
The basic migration of Liquid Data 1.1 to 8.1 is straightforward. This section provides instructions for such a migration which includes:
Before installing Liquid Data 8.1, the WebLogic platform and domains you will be using with Liquid Data 8.1 must be installed and configured properly. Specifically:
WL_HOME
used by WebLogic Platform 8.1.Note: If you are using Liquid Data with more than one domain, you must follow these procedures for each domain that you want to migrate to Liquid Data 8.1.
In order to migrate from Liquid Data 1.1 to 8.1 you must create a new Liquid Data installation.
Follow the appropriate preparation, installation, and post-installation steps described in the Installation Guide.
If you are using Liquid Data in a production environment, deploy Liquid Data to the appropriate WebLogic Platform 8.1 domain as described in the Deployment Guide. Liquid Data 8.1 supports deployment to new and existing domains through the WebLogic Domain Wizard.
Through this wizard you can select the appropriate Liquid Data WebLogic deployment such as WebLogic Portal (WLP), WebLogic Integration (WLI), WebLogic Server (WLS), and WebLogic Workshop.
Perform the following steps in the order presented to migrate your 1.1 Liquid Data repository and any Liquid Data applications you have created to Liquid Data 8.1.
See also What Liquid Data Does Not Import or Export, in the Administration Guide.
Examples used in this chapter assume that the Liquid Data 1.1 directory is located at:
/opt/prod/bea_70SP2/user_domains/ld_domain
These examples also assume that the new Liquid Data 8.1 installation is location at:
/opt/prod/bea_81/user_domains/ld_domain
When the discussion relates to the WebLogic Server 7.0 SP2 installation, <WL_HOME_70SP2>
is used. Similarly, <WL_HOME_81>
represents the WebLogic Server 8.1 installation.
The symbolic name <LD_REPOSITORY>
represents the Liquid Data repository and its contents.
This section describes prerequisites and provides specific instructions for migrating Liquid Data 1.1 data sources to Liquid Data 8.1.
Note: Security settings and cache policies are automatically transferred along with data sources.
Perform the following steps to export Liquid Data 1.1 data sources:

/opt/prod/bea_70SP2/user_domains/ld_domain
/ld_repository/import_export
This section describes prerequisites and provides specific instructions for copying the Liquid Data 1.1 repository to Liquid Data 8.1
Perform the following steps to migrate your Liquid Data repository:
Copy the Liquid Data 1.1 repository directory structure to the new repository location.
You can use the Administration Console to determine the name and location of your 1.1 Liquid Data repository. For details see Configuring Liquid Data Server Settings in the Administration Guide.
Using the example directory structure you would copy:
/opt/prod/bea_70SP2/user_domains/ld_domain
/ld_repository
/opt/prod/bea_81/user_domains/ld_domain
This section describes prerequisites and provides links to instructions for recreating Liquid Data 1.1 JDBC connections and data sources under Liquid Data 8.1.
To migrate your Liquid Data JDBC connectivity to relational databases, first determine the directory location of the 1.1 Liquid Data domain you are migrating from, as follows:
/opt/prod/bea_70SP2/user_domains/ld_domain
/config/ld_domain
For detailed information on managing JDBC data sources and connections, see Managing JDBC Connectivity in the WebLogic Server Administration Guide and Migrating Domains Using the Configuration Wizard in the WebLogic Platform Release Notes: 7.0 Service Pack 2.
This section describes prerequisites and provides specific instructions for moving Liquid Data-related project files, applications, custom functions, and web services not generated by Liquid Data from Liquid Data 1.1 to 8.1.
Move and deploy any Liquid Data 1.1-related project files, applications, custom functions, and web services not in the repository.
For additional information on such migrations see discussions in the Liquid Data Administration Guide on:
This section describes prerequisites and provides specific instructions for importing Liquid Data 1.1 data sources into Liquid Data 8.1.
If you have followed instructions in Step 2: Copy the 1.1 Liquid Data Repository to 8.1, your 8.1 data source file myDataSource.xml
is available under <WL_HOME_81>
in the following location:
/opt/prod/bea_81/user_domains/ld_domain/ld_repository
/import_export
To import the Liquid Data data sources follow the procedure described in the Liquid Data 1.1 Administration Guide:
http://download.oracle.com/docs/cd/E13190_01/liquiddata/docs10/admin/impexp.html#1044952

This section describes how to test the migration from Liquid Data 1.1 to Liquid Data 8.1 by verifying hat your 1.1 metadata is available under Liquid Data 8.1.
Once your query has been loaded, you can run it. See Testing Queries in Building Queries and Data Views.
When you are sure your migration from Liquid Data 1.1 to 8.1 has been successful, you are ready to start using Liquid Data 8.1. It is suggested that you retain your Liquid Data 1.1 installation for a reasonable time and then archive it for safekeeping.
