My database was moved into v08 from v05. I noticed the Compatibility remained at 90. Is it best to leave it there or would it be better to change it to 100? I have a web application and windows application running against this db. Will changing the Compatibility affect them? Also, I have two other dbs that will be moved to v08. Besides web applications, they have SSIS pkgs running against them. Will there be issues there if I up the Compatibility to 100?

You should change the compatibility level to 100 in a test environment and when you are satisfied that the application works as desired still, you can then change it in production.

Switching compatibility levels after an upgrade is a manual step, the upgrade never moves the compatibility level up for you.
