Red Hat SYSTEM 8.0 - MIGRATION GUIDE 7.X TO 8.0 Manual page 15

Considerations Before Migration
• An SSL port for the administrative console or admin services
• A web server port (Tomcat for CA, DRM, OCSP, and TKS subsystems, Apache for the TPS and RA
subsystems)
However, Certificate System versions older than 8.0 used only three ports, a web server port, an
unsecure port, and a single SSL port. This means that special care needs to be taken when migrating
to Certificate System 8.0 from any Certificate System 7.x server. Either the port configuration must be
updated in the 7.x server configuration, or the Certificate System 8.0 subsystem has to be installed
using pkicreate to specify a single SSL port. Using pkicreate is described in the Installation
Guide, and reconfiguring ports is described in the Administrator's Guide.
Because port numbers are stored in the server.xml file, which is unaffected by subsystem
migration, port numbers can be changed between instances without difficulty.
About Usage Examples
All examples assume that a 7.3 instance is being migrated, so default directory paths and file names
correspond to the 7.3 subsystem versions. Make sure that the information in your migration steps
correspond to your appropriate version and platform.
All examples assume that the new passwords are the same as the old passwords.
Backing up Existing Data
Before migrating any Certificate System instance, back up the information for the Certificate System
instance, including the security databases in the alias/ directory and all data stored in the internal
LDAP database. When the backup process is complete, then stop the old Certificate System, Directory
Server, and Administration Server instances.
