5 Preparing software for migration
Verifying licenses for software to be migrated
Before performing 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 operating systems license agreements might require you to purchase a
new license for the destination server.
IMPORTANT: Servers with Windows Original Equipment Manufacturer (OEM) licenses are not
supported for migration. For licensing questions, contact HP support. See “Support and other
resources” (page 66) .
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 performing the migration, you need to manually disable, reconfigure, or uninstall other
firewall products. If you reconfigure a firewall product, you will be required to uninstall 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 performing a migration, then 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 integrated Lights Out (iLO) for auto destination 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
