Many options are available for upgrading an existing AIX environment. You can
use the following methods to upgrade an existing environment:
- Using a mksysb backup
- If you can migrate your server to AIX 5L™ Version 5.3 with the 5300-08 Technology Level or
later, you can create a mksysb backup of
the older server. You can then use the mksysb command to reinstall AIX on the new server.
- Using alternate disk migration
- If you want to decrease the amount of time that your production
environment is down, you can use the nimadm command to perform an alternate disk migration. This method requires
more resources than the other methods. You must have an existing AIX Network Installation
Management (NIM) master that is running the same version of AIX that you are migrating
the new server to.
Note: The 2849 card that is compatible with an IBM® eServer™ i5 server, is not compatible
with an AIX logical
partition.
