Yes you can make that change. However, I'd strongly suggest that you use the Upgrade Advisor as @Squirrel mentions as well as perform any type of regression tests that you might have available.

I don't know of any script/tool that you can use to definitely say that you have a compatibility issue other than Upgrade Advisor.

You can also check here: http://technet.microsoft.com/en-us/library/bb510680(v=sql.100).aspx to see what the differences are between 80/90/100.

Hope this helps!

You can use the Upgrade Advisor.

Using Upgrade Advisor to Prepare for Upgrades

Best is still do this in your development environment and test out your application after changing it

New code box

There's a new way to format code on the site - the red speech bubble logo will automatically format T-SQL for you. The original code box is still there for XML, etc. More details here.
