ABSTRACT:
An apparatus, program product and method improve software updates processes within a logically partitioned environment by creating a new, proxy partition having substantially the same operating characteristics as an original partition, in addition to an updated software application. Network connectivity is transferred seamlessly over from the original partition to the new partition. While “hidden” from the network, the original partition continues to operate with reduced resources as the new partition takes over production operations. As such, the original partition remains in a ready state against the possibility of a problem arising with the new partition. In such an instance, network connectivity is transferred back over to the original partition, which resumes production operations as before.
