5 Preparing software for migration

Verifying licenses for software to be migrated

Before you perform a migration, review all hardware, operating system, and application licenses on the source server and acquire all valid licenses necessary for the destination server. Some hardware, software, and OS license agreements might require you to purchase a new license for the destination server.

IMPORTANT: Servers that have Windows OEM licenses are not supported for migration. For licensing questions, contact HP support. For information about HP support, see “Support and other resources” (page 73).

Migration security

Disabling firewalls

The source server Microsoft Windows firewall or Linux firewall and SELinux are disabled automatically by server migration when a migration begins. The firewall and SELinux (if applicable) are re-enabled after the migration is completed.

Before you perform the migration, you must manually disable, reconfigure, or remove other firewall products. If you reconfigure a firewall product, you will be required to remove the product before migration and reinstall it after migration.

If the firewall is not disabled or configured properly on the source server, application station, and virtual machine hosts before a migration, the source server, application station, and virtual machine hosts might not be able to communicate. Symptoms of this issue can include the following:

•The application station cannot detect the source server migration Agent for migrations.

•The source server hangs after booting into exclusive mode during migrations.

The following TCP ports are used for Insight Control server migration:

•Port 51124—For communication between the Insight Control server migration Web Service and the Insight Control application service using Secure Sockets Layer (SSL)

•Port 51125—For communication between the Insight Control server migration Web Service and iLO for autodestination boot

•Ports 51125 and 51126—For communication between the Insight Control server migration Application Service and the migration agent on the source server

•Ports 51125 and 51126—For communication between the Insight Control server migration Application Service and the migration agent on the destination server

•Port 51126—For communication between the migration agents on the source server and destination server

•Port 51127—For use on the application station for Insight Control server migration Web Service

•SSH port 22—For Linux migrations
