PI (XI 7.0) Installation and Post Installation Guides

We have installed XI 3.0 with previous clients, and we are trying to install XI 7.0 (PI) for a client on Windows 2003 SQL server. We looked for installation documents in the service.sap.com, but we were confused about which documents to follow.

Has anyone installed PI (XI 7.0) from scratch? If yes, could you provide us documents regarding installation and post installation steps. What are the differences in installing XI 3.0 and PI?

You help is greatly appreciated.

Cheers,

Karma
