SQL Server 2008 R2 and Full-Text Indexes

Hi everyone,

We're deploying new database servers running SQL Server 2008 R2 as part of our Tessitura v11 project. I am currently restoring an impresario database running on SQL Server 2005 to a server running SQL Server 2008 R2.

My questions relate to the full-text indexes. Specifically:

1. Which full-text upgrade mode is recommended? Import, Rebuild, or Reset? 
2. It sounds like a rebuild is required to take advantage of the last features, like new and enhanced word breakers. Is it advisable to do this at some point, even if an Import is initially done?
3. Are there any other full-text issues I should be considering?

Thanks for your help!
