Steps to unlock 'sa' account and resetting the password.

1. Open SQL Server Configuration Manager

2. Select SQL Server Services -> 'SQL Server' service.

5. Save the settings and Restart the service.

In most of the cases, generally you create items in master database and publish to web/production data. However, sometimes few items are in web database and not in master. Reason can be anything, like you might have deleted it in master but did not publish the parent item or due to some other reason.

If you are thinking, you will create package from web and deploy it in master, that will not work. :-) When you create package from master, it installs the items in master only and same is the case with web.

Right and easy way to do is Transfer the item. Yes, you read it right. There is a provision in Sitecore to transfer the items from one database to another.

Select the item which you want to transfer from one database to another. Right click on it and then select Copying. Click on Transfer. see screenshot

Once you click on Transfer, it opens up a popup box. Click 'Next'. see screenshot

After clicking on next, you have to choose the database where you would like to transfer the…
