–Import Java project into WebSphere Commerce V5.6 development environment in WebSphereCommerceServerExtensionLogic

6.Generate deployment code

–For full test environment: From the EJB JAR pop-up menu, click Generate > Deployment and RMIC Code

–For lightweight test environment: From the EJB JAR pop-up menu, click Generate > Test Deployment Code

7.Generate Access beans

8.Code Changes

–Fix any WSAD compilation errors

9.Migrate WebSphere Commerce Suite V5.1 development environment instance: You would need to copy the product.xml and product.dtd file to the <WCS51_home> /xml directory and update: edition, release, fixpack and path before you migrate instance

10.Migrate database schema and unencrypted data:

First run the database migration script in -precheck mode to find any inconsistencies which could be discovered with actually migrating the data.

This does not, obviously, guarantee the discovery of all the issues you may find while doing the actual database migration. As such you may want to position your first attempt at database migration to discover any additional database inconsistencies. The migration script does not interrupt when it finds any issues and this could allow the first migration run to act as a more thorough check for database consistency for migration. After the first test-run, you can restore the database and fix the problems discovered and re-run the migration scripts. You may want to tune database migration performance if it took a long time during the first run. Please refer to the behavior of migration scripts found in Appendix C, “Migration scripts” on page 255.

In order to ease the task of migrating the database second time over we created custom scripts to perform preparation and migration tasks. These scripts can be found in Appendix C, “Migration scripts” on page 255.

11.Migrate encrypted data: At this step you migrate user password data and which you could have chose to encrypted viz, credit card data.

12.Setting up Test environment and testing the migrated environment

3.6.2 Detailed overview of production environment migration

In our scenario since we performed Switch-Over migration we installed and configured WebSphere Commerce V5.6 environment on another machine, say
