Migrating delta data
If you continued to use your existing BMC Cloud Lifecycle Management solution while upgrading to 3.1 in a staging environment, you must migrate the delta data created in 2.1 to 3.1. Delta data refers to the data changes that might have occurred on the production server while you upgrade 2.1 products to 3.1 on the staging server.
The Delta Data Migration Tool is bundled with the BMC Remedy Migrator application. After the delta data is migrated to 3.1, the staging server is converted to the production server. You must perform the following tasks to migrate the delta data:

Steps for performing the delta data migration
You must perform the following steps in the order listed to successfully complete the delta data migration.
Note
BMC recommends that you perform these tasks in a non-production environment, for validation purposes, before you perform the upgrade for the staging and production servers.
- Prepare the destination server, which might be the staging Cloud Database or Enterprise AR System server, for delta data migration.
- Run the Delta Data Migration tool to migrate the delta of data that changed during the staging server upgrade.
- Run the migration scripts to normalize the data in your upgraded BMC Cloud Lifecycle Management environment.
Before you begin
Before you migrate the delta data, ensure that you fulfill the following requirements.
