Migrating From Sitefinity 3: Disqus Comments

This post is part of a series exploring my migration from Sitefinity 3 to 4.4. Some of this information may become obsolete as newer versions are released. Always watch the official Sitefinity website for the latest info.

The final step in migrating this site from Sitefinity 3 was to restore the Disqus comments on my blog. As I mentioned sometime ago, I replaced the Sitefinity comments with Disqus and have used it ever since.

Unfortunately, Disqus uses the Url as the identity key for each discussion. As I’ve mentioned throughout this series of migration posts, I am using the new Sitefinity blog Url format, which means all my comments were lost. Disqus saw the new Urls and assumed these were new discussions.

Disqus Tools

Fortunately, Disqus has you covered with several helpful migration tools of their own for situations just like this.


There is a Domain Migration Wizard, helpful if you are moving to a different domain. You can also upload a CSV file that manually maps old Urls to the new ones.

The easiest solution by far however has to be the Redirect Crawler. This tool will navigate through the original Disqus Urls and if there is a 301 redirect, update the identity Urls for the discussion so that they transfer to the new Url.

Thanks to the IIS Url Rewrite Module, this is already done, and I simply needed to run the tool and wait for it to crawl my site. Now all my old Disqus discussions have been redirected, and the existing comments are now visible on all my old posts.

Wrapping Up

And with that, my migration is complete! I transferred all my old pages and posts into a brand new theme. I migrated some content to my business site Page Init Solutions. I took advantage of the slick new Blog Url format, using a custom Blogs Provider to take full control of the Url format. I took care of redirecting all the old Urls, and imported all my old Disqus comments.

I hope that anyone else going through this process finds this series helpful, and if you have any questions, you can always consult the Sitefinity Migration Discussion Forum, or feel free to send me your questions as well!

Upgrading From Sitefinity 3: Url Rewriting

This post is part of a series exploring my migration from Sitefinity 3 to 4.4. Some of this information may become obsolete as newer versions are released. Always watch the official Sitefinity website for the latest info.

As part of the migration of my website from Sitefinity 3, I updated both the Url format for pages (now extensionless) and blog posts (also extensionless and different format) for better readability and SEO. This of course would leave a wake of broken links and search results linking to the old Urls.

There are many options available to resolve this, such as developing a custom HttpHandler to intercept the old Urls. Fortunately, there is a fantastic tool that handles all of this for you.

IIS Url Rewrite

IIS Url Rewrite is an extension for IIS that enables a wealth of Url handling features, including the two I needed for my site: Rewriting and Redirecting.


As part of my website update, I moved some of the content such as the Sitefinity 3 Toolkit info to my company website Page Init Solutions. So I need to redirect all these requests from this site to that one.

The Url Rewrite module has an option for creating redirects, which you can manage in a friendly GUI for IIS.


You can also manage this directly in the web.config file. Here are some of the redirects I put in place using the module.

                <clear />
                <rule name="Redirect rule1 for PageInit">
                    <match url=".*" />
                    <conditions logicalGrouping="MatchAll" trackAllCaptures="false">
                        <add input="{PageInit:{REQUEST_URI}}" pattern="(.+)" />
                    <action type="Redirect" url="{C:1}" appendQueryString="false" />
                <rewriteMap name="PageInit">
                    <add key="/software.aspx" value="http://pageinit.net/software" />
                    <add key="/software/Sitefinity/Sitefinity_Toolkit.aspx" value="http://pageinit.net/software/sitefinity-toolkit" />
                    <add key="/software/jQuery/Banner_Swapper.aspx" value="http://pageinit.net/software/jquery-banner-swapper" />
                    <add key="/software/Sitefinity/Sitefinity_Password_Recovery.aspx" value="http://pageinit.net/software/sitefinity-3-password-recovery-tool" />
                    <add key="/blog.aspx" value="http://www.selarom.net/blog" />
                    <add key="/contact.aspx" value="http://www.selarom.net/contact" />

This allowed me to easily map old Urls to new, including the old .aspx extensions for pages. Adding a new redirect is as simple as adding a new entry in the list.

Url Rewriting

The new blog Url format makes for SEO friendly as well as functionally useful Urls. They are, however, starkly different from the original format from Sitefinity 3, and clearly, redirecting every single post individually is not an ideal solution.

Fortunately, the Url Rewrite Module also has excellent support for Url rewriting using Regular Expressions. Using Regex, I was able to easily rewrite the old format of /YYYY-MM-DD/Title to the new /YYYY/MM/DD/Title format now used by Sitefinity. I was even able to rewrite some of the urls for the list of blogs by Tag and Category.

Admittedly, working with Regular Expressions is probably one of my weakest programming skills, and despite what everyone keeps saying on Twitter, it does NOT get easier the more you do it! That being said, here are the Regex rewrites I created for this site. If anyone has suggestions for improving or consolodating them, by all means let me know!

 <rule name="BlogPosts" stopProcessing="true">
                    <match url="^(.*)/([0-9]{4})[-]([0-9]{2})[-]([0-9]{2})/(.*)$" />
                    <conditions logicalGrouping="MatchAll" trackAllCaptures="false" />
                    <action type="Redirect" url="{R:1}/{R:2}/{R:3}/{R:4}/{R:5}" />
                <rule name="BlogYear2Month">
                    <match url="blog\.aspx$" />
                        <add input="{QUERY_STRING}" pattern="Year=([0-9]{4})" />
                        <add input="##{C:1}##_{QUERY_STRING}" pattern="##([^#]+)##_.*Month=(\d{2})" />
                    <action type="Redirect" url="blog/{C:1}/{C:2}" appendQueryString="false"/>
                <rule name="BlogYear1Month">
                    <match url="blog\.aspx$" />
                        <add input="{QUERY_STRING}" pattern="Year=([0-9]{4})" />
                        <add input="##{C:1}##_{QUERY_STRING}" pattern="##([^#]+)##_.*Month=(\d{1})" />
                    <action type="Redirect" url="blog/{C:1}/0{C:2}" appendQueryString="false"/>
                <rule name="BlogYear">
                    <match url="blog\.aspx$" />
                        <add input="{QUERY_STRING}" pattern="Year=([0-9]{4})" />
                    <action type="Redirect" url="blog/{C:1}" appendQueryString="false"/>
                <rule name="BlogTag">
                    <match url="blog\.aspx$" />
                        <add input="{QUERY_STRING}" pattern="tag=(.*)" />
                    <action type="Redirect" url="/blog/-in-Tags/Tags/{C:1}" appendQueryString="false"/>

Wrapping Up

The IIS Url Rewrite Module is a fantastic tool for ANY website that has a need for rewriting or maintaining Urls, and is highly recommended for anyone attempting to migrate to the latest verion of Sitefinity.

Finally, here are a few resources I found extremely helpful in preparing these rewrites and redirects:

Upgrading From Sitefinity 3: Blog Urls and Providers

I also mentioned in the previous post that although your original Urls for existing pages and content items are preserved, any new published blog posts will fallback to the default format. This also happens to any existing content that you republish.

Upgrading from Sitefinity 3: Extensionless Urls

By default, the Sitefinity Migration tool imports content items and pages with their original urls fully intact. That means all your old urls and SEO remain intact, including the original .aspx extensions from the old website.

Instead of trying to find a way to force Sitefinity to use my old url format, I decided it was much better (not to mention cleaner and more SEO friendly) to have my old urls convert to the new format.

Upgrading From Sitefinity 3 to 4.4

Now that I’ve fixed my issues with Windows Live Writer and Sitefinity, I can finally take some time to talk about the migration process itself, and hope that it will be helpful to anyone else going through the same process.
