Upgrade MOSS 2007's SQL 2005 to SQL 2008?

Hi,

I have a MOSS 2007 (with SP1) setup on Windows Server 2003 and SQL 2005 installed. I would like to implement SQL 2008's TDE feature to make my data more secure. 

I read that you can upgrade SQL 2005 to SQL 2008. Can I simply upgrade my SQL 2005 to SQL 2008?  

Will it still work with SharePoint? Has anyone tried something like that?

Hope someone can assist.

Thank you.

Regards
GM
