I assume your new PC has
SQL Server
installed. So, what you can do is as follows:
1. Take backup of
SQL Server
database(s) from the source PC.
2. Restore the backups into the destination PC's
SQL Server
database.
3. Update the
ConnectionString
property value of your .NET projects so that, the
ConnectionString
points to the new Database server, along with correct database names and credentials.

SQL Server
databases.
