In-Place Upgrade

The target server is installed in the same installation location as the source server. You can choose to perform this type of upgrade if you wish to install the configuration (that is, the domains) in the same location as before. In this scenario, you install the binaries in the same location as the existing binaries using the installer.

An in-place upgrade involves the following sequence of tasks:

1. Upgrading Communications Server Runtime Binaries

2. Upgrading Configuration and Deployed Applications.
