This content database has a schema version which is not supported in this farm

With the Corrupted Master Database in the existing server, We have taken a backup of the Web applications Content Database (MDF & LDF) files, and attached  to the New Server (SQL Restore).

On the next step, We have a created a Web Application in the port 80 with different Host Headers and detached the content database (Newly Created) from the web application. After that We attached the existing content database with the newly created web application after that I got error this Error.

This content database has a schema version which is not supported in this farm”

 The reason was database which I was trying to attach to SharePoint farm it was new version of SharePoint than the current one I have. So I have to upgrade our SharePoint farm to new version, so downloaded the SP1+August 2011 CU update (http://technet.microsoft.com/en-us/sharepoint/ff800847.aspx ) and install on the SharePoint 2010 server and run the Configuration Wizard to upgrade farm and then try to attach the database again, and it was successfully attached in SharePoint.

After that I moved all the webpart solutions to SharePoint server 2010 add webpart solution one by one SharePoint 2010 server and through CentralAdmin started deploying it.

And my site started working ………………
