There may be cases
where you will be doing a remote migration
to a new hardware configuration. This new server may have different
requirements from the current environment you are migrating from.
Generally,
here are some key points to consider.
- Prerequisites
WebSphere Portal detailed system requirements
Source environment:
- Revisit the hardware the software requirements for the platform
you are migrating from. Ensure that you are still in a fully supported
environment.
- Make sure that you are current with, at least,
the last two maintenance
levels for that platform.
- Be aware of the current overall
performance and throughput. You should
know what is the current activity on your WebSphere® Portal Express® server.
- Make
sure that you have detailed information about your entire
environment.
- Identify all the systems your WebSphere Portal Express server connects to.
- Keep a detailed list of all the credentials and connection information
as well as the services provided by the other systems.
- If
firewalls are involved, make sure that you note ports, IP addresses,
and host names used.
Target environment:
- Review the system requirements for your new environment.
- Review the supported migration paths.
- Will this new system
be dedicated as a WebSphere Portal Express server or it will be shared
with other services?
- If shared, be aware of potential resource
conflicts such as ports
as well as overall system performance.
- Make sure
that you are at a supported maintenance level.
- Be mindful
of the projected WebSphere Portal Express server activity. Once
migrated, or even during the testing phase of your migration, you
should
be able to compare performance data between your current and new WebSphere Portal Express servers.
Architecture:
- Your target environment must be on the
same system architecture
than your source environment for migration. Migrating to a different
architecture is not supported.
