حال با استفاده از ابزار ASP.NET Configuration دو کاربر جدید بسازید: oldAdminUser و oldUser.

نقش جدیدی با نام Admin بسازید و کاربر oldAdminUser را به آن اضافه کنید.

بخش جدیدی با نام Admin در سایت خود بسازید و فرمی بنام Default.aspx به آن اضافه کنید. همچنین فایل web.config این قسمت را طوری پیکربندی کنید تا تنها کاربرانی که در نقش Admin هستند به آن دسترسی داشته باشند. برای اطلاعات بیشتر به این لینک مراجعه کنید.

پنجره Server Explorer را باز کنید و جداول ساخته شده توسط SQL Membership را بررسی کنید. اطلاعات اصلی کاربران که برای ورود به سایت استفاده می‌شوند، در جداول aspnet_Users و aspnet_Membership ذخیره می‌شوند. داده‌های مربوط به نقش‌ها نیز در جدول aspnet_Roles ذخیره خواهند شد. رابطه بین کاربران و نقش‌ها نیز در جدول aspnet_UsersInRoles ذخیره می‌شود، یعنی اینکه هر کاربری به چه نقش هایی تعلق دارد.

برای مدیریت اساسی سیستم عضویت، مهاجرت جداول ذکر شده به سیستم جدید ASP.NET Identity کفایت می‌کند.

مهاجرت به Visual Studio 2013

• برای شروع ابتدا Visual Studio Express 2013 for Web یا Visual Studio 2013 را نصب کنید.
  
• حال پروژه ایجاد شده را در نسخه جدید ویژوال استودیو باز کنید. اگر نسخه ای از SQL Server Express را روی سیستم خود نصب نکرده باشید، هنگام باز کردن پروژه پیغامی به شما نشان داده می‌شود. دلیل آن وجود رشته اتصالی است که از SQL Server Express استفاده می‌کند. برای رفع این مساله می‌توانید SQL Express را نصب کنید، و یا رشته اتصال را طوری تغییر دهید که از LocalDB استفاده کند.
  
• فایل web.config را باز کرده و رشته اتصال را مانند تصویر زیر ویرایش کنید.
