Technical Requirements : .Users must be able to access upgraded and nonupgraded sites during the upgrade process. .All PerformancePoint data and dahboard information must be migrated to SharePoint Server 2010.

Security Requirements:

sers must be able to access all documents during the upgrade process.

I am evaluating whether to implement an inplace upgrade to SharePoint Server 2010. I need to identify how many index partitions will be created during the inplace upgrade. How many index partitions will be created?

Can somebody explain me more about index partitions?

Your question is only how many index partitions are created? Automatically? None. Index partitions only spread your search application index over several partitions, hence speeding up your searches (and decreasing the size and needed RAM for the DB on the server holding a subset of your index). There is a limit of 20 index partitions per search application.

You can read some about Search Architecture and about indexing.
