Upgrading Remote Desktop is just like installing it for the first time. The only difference is that the final button in the installer reads "Upgrade" rather than "Install." The installer upgrades existing software to its latest version, imports previously created lists, and restarts the underlying processes after completion.

See Installing the Remote Desktop Administrator Software, for detailed instructions.

If you are upgrading from version 1.2 and changing administrator computers, you'll need to transfer your existing computer lists. See Transferring Old v1.2 Computer Lists to a New Administrator Computer. Be sure to transfer your lists from Apple Remote Desktop v1.2 to the new computer before upgrading to Apple Remote Desktop 3. If you upgrade from version 1.2 to version 3.1 on the same administrator computer, this list migration is done for you.
