This section gives an overview of the things you need to consider
when planning your migration strategy. For detailed instructions on
migration, see Software installation.
Migration strategies
If
you already have applications in production, you need to consider
your migration strategy:
- If you have more than one Power System, and
can install the new release on one system while keeping your applications
running on another, you can follow the instructions for first-time
installers, and then migrate your applications afterwards.
- If you are planning to install on a new Power System and migrate, you can follow the instructions
for first-time installers, and then migrate your applications afterwards.
- If you have only one Power System and are
planning on upgrading it to the new release, you need to migrate your system in-place. Follow
the instructions in this information carefully to minimize the downtime required for migration and
installation. If you are migrating in-place, it is especially important that you prepare thoroughly
beforehand. Make sure you schedule the migration to happen at a time when applications are least
active.
