Compatibility level of Database Properties of sqlserver 2008

When I restore the databases from sqlserver 2005 to 2008, I see the database properties (options) are defaulting to SQL Server 2000(80). Do I need to change the Compatibility level to SQL Server 2008 (100) for all databases.

Yes, you will have to make this change yourself. If this is a thirdparty vendor database you might want to double check with them as well to ensure they support the upgraded compatibility level. I have only had two vendors out of several hundred where this was an issue.

If the database was already at level 80 when in 2005, then yes you will need to change the level to 100.

There are T-SQL differences between 2000 and 2008, but I'm sure you've already contemplated those if you are upgrading your server?

I'd also check the page verification option as this was defaulted to TORN_PAGE_DETECTION in 2000, whereas 2005 and above it is CHECKSUM - it is worth changing this too!

You might also want to run [DBCC CHECKDB WITH DATA_PURITY][1] if it was at 80. It's best to do a test migration and work out the kinks/see what pitfalls may be in store.

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.
