IN place method for the database upgrade SQL 2000 to 2008,

Can I go for below one of the steps?

first database brings to single user in SQL 2000 database, then start upgrade installation on sql server 2008. once completed installation then apply SP3, finally database brings to multi_user mode

I am not sure what that would do to the installer. If the installer tried to open multiple connections it would fail, and it may in fact change the mode itself during the upgrade process. Not sure about 2000 but 2005 and the newer will deny connections during critical portions of an upgrade stating they are in 'administrative mode' or something like that.

Is your goal simply to guarantee users cannot connect to the database instance during the upgrade? If so then if you only have network clients to worry about then consider disabling all protocols except Shared Memory to essentially take the database instance off the network before doing the upgrades.

I would uninstall and do a clean install. I have seen too many problems with upgrades, especially if a between-version is skipped.

No... Don't use the single user connection mode for this because if you lose connection for even a second, a web service will grab the connection and you'll be out of luck.

The proper way to do this is to make sure that all of the web services pointing to the server have been cleanly shut down.

Thanks for your replay...

Mr. Jeff comments is good method stoping IIS services instead of using single user mode in database side.

I have done migration activity last weekend and application aslo working fine with SQL SERVER 2008, but i am did wrong method by used single user mode at databse side during IN PLACE upgrade action.

I should take care next time if any server migration action.

you could turn on your firewall and block incoming traffic to the port sql server is listening on
