Upgrade from 1.9 to 2.3, SEO URL Changing

Hello,

My website is currently running on 1.9 and I want to upgrade to 2.3. I notice that the url of 2.3 is without the aspx and some of the numbers are changed to be different. I have so many backlinks pointing to my website. If I do the upgrade, is there a way that I can keep all my url to be the same? If not, then I would lose all my inbound links.
Please help, thanks
Toan

All links have new formats in 2.X version. But no worries about 1.X links. All of them will also work in 2.X

Hello,
no, the links with .aspx extension going to 404 errors and what about search engines cache?

Please edit Global.asax (in source)

add to namespaces

using System.Text;
using System.Text.RegularExpressions;

Find Application_Error method and add after LogException(Server.GetLastError()); code

//added
            Exception ex = Server.GetLastError();
            //added for 404 error
            if (ex is HttpException)
            {

                if (((HttpException)(ex)).GetHttpCode() == 404)
                {
                    HttpContext context = (sender as HttpApplication).Context;                 

                    if (context.Request.PhysicalPath.EndsWith(".aspx", StringComparison.OrdinalIgnoreCase))
                    {
                        var webHelper = EngineContext.Current.Resolve<IWebHelper>();
                        // Get current HttpApplication Request
                        HttpApplication hxa = (HttpApplication)sender;

                        //Get Incoming Request for page.
                        string originalUrl = hxa.Context.Request.Url.ToString();

                        string patternProduct = String.Empty;
                        string patternCategory = String.Empty;
                        string patternManufacturer = String.Empty;

                        Match matchProduct = Regex.Match(originalUrl.ToLower(), patternProduct);
                        Match matchCategory = Regex.Match(originalUrl.ToLower(), patternCategory);

                        //@redirect to new url                      

                        // Try and Check for redirect

                            if (!String.IsNullOrEmpty(newUrl))
                            {
                                context.Response.Clear();
                                context.Response.StatusCode = 301;
                                context.Response.AppendHeader("location", newUrl);
                                context.Response.End();
                            }
                            else
                            {
                                Response.StatusCode = 404;
                            }
                        }
                        catch (Exception)
                        {
                            //Redirect to page not found if we have an error
                            hxa.Response.AddHeader("Location", webHelper.GetStoreLocation());

                    else
                    {

Most likely you need make changes, eg. if your url`s of pages in 1.x versions had pattern "../product/.. "you need change pattern to

@"/product/(\d{1,10})-([A-Za-z0-9\-]+)\.aspx$"

This is a simplest method, but better implementation will be: get product by id and redirect to new. Code was tested on localhost and return correct 301 redirect to new.

It works fine. Test it on our [url=demo.nopcommerce.com/]demo site[/url]. http://demo.nopcommerce.com/products/1-sdf.aspx will redirect you to http://demo.nopcommerce.com/p/1/5-virtual-gift-card.

P.S. All redirects (permanent) are handled by the following file: \Presentation\Nop.Web\Controllers\BackwardCompatibility1XController.cs

It`s not working properly.

Sample, in old system demo was url http://demo.nopcommerce.com/p/1-5-virtual-gift-card.aspx (productId = 1, SEName=5-virtual-gift-card).

Please try go to http://demo.nopcommerce.com/p/1-5-virtual-gift-card.aspx you will get custom error with 302 status code (it must be 404 or 301 with redirect to http://demo.nopcommerce.com/p/1/5-virtual-gift-card)

If i upgrade system on my site, http://www.climatik.dp.ua/p/30-dekker-dsh105rl.aspx it will not work, tested on localhost.

Thank You

It works fine!

You have non-standard URLs in 1.90 (maybe, you changed it). So if you want to redirect from .../p/1-productname.aspx to the new URL, then follow the next steps:
1. Open \Presentation\Nop.Web\Infrastructure\UpgradeRouteProvider.cs
2. Find

routes.MapRoute("", "products/{id}.aspx",
   new { controller = "BackwardCompatibility1X", action = "RedirectProduct"},
   new[] { "Nop.Web.Controllers" });

and replace it with

routes.MapRoute("", "p/{id}.aspx",
   new { controller = "BackwardCompatibility1X", action = "RedirectProduct"},
   new[] { "Nop.Web.Controllers" });

Yes, i changed url pattern in old system.

Thank You Andrei

Great work by all nopcommerce developers. Well done.
