SSRS and SharePoint 2010

I have use SSRS 2008 before installing SharePoint 2010. I dig around th开发者_Go百科at there is a way to switch the mode from native to sharepoint integration but the question now is when i did my swicth did all my reports in native mode are gone? need to be rebuild?

I was exactly looking for the same thing.

Apparently you need to create a new database in integrated mode, and then upload all your reports (you can script this task). I think it's also needed to then manually recreate subscriptions and any other configurations....
