We are going to talk about moving your content from Different CMS to WordPress. So if you use Blogger, Drupal or Joomla you can move your content automatically, this is a good choice if you have lots of posts or pages to move and don’t wish to start fresh.
If you have an static HTML site, or a site in any CMS that has few pages or post I strongly recommend to copy and paste the content, so you have the chance to clean the code, in case there are images optimize them, if you are using shortcakes, maybe review if they work in WordPress
This automated process is good if you have an amount of content that you don’t want to deal manually. And I will place that number about 35/40 posts, fewer than that I can find the patience and/or courage to do it by hand. There is great article in Smashing Magazine about the steps to do it, and what needs to be revised.
The first site to learn about migration to WordPress you may want to check the Codex – https://codex.wordpress.org/Importing_Content
It has a very long list of CMS that can be migrated into WordPress and more information regarding how to proceed in every case.
From Drupal to WordPress
You can find some plugins like CMS2CMS it has no good reviews, but also, the free version it has a limited number of pages, so like I said, if you have a small amount of content go by hand, the pro version that allows unlimited amount of pages is not free and is about $39
It supports Drupal 5/6/7 and WordPress 4
From Blogger to WordPress.
You can do this going to the blogger dashboard and the go to settings -> Other, under the Blog Tools, you can click on the “Export Blog” link. You will se a pop up to download the information in a XML File.
Once you have that file in your computer, you may go to your WordPress dashboard, Tools, Import and click in “Blogger” that will prompt to install the WordPress importer, once you have that importer installed and active you need to choose the XML file that you downloaded and then click in “Upload File & Import” Then follow the questions you will see regarding the author.
Then setting up the permalink to the same structure you had in blogger, and that will be “month and name”
From Joomla to WordPress
One of the best ways to do it is with the FG Joomla to WordPress plugin, it has great reviews, it has been tested on large databases from Joomla 1.5 through 3.4, and you can move a website using the free version, although the premium version has great features like migrating authors users with their passwords. Thing is, the premium version is not that expensive, it will set you back $35. You can see the differences here
So there you go, like I said, if it’s a small website, you may want to do it by hand, if it’s a large website with hundreds of posts or pages, you may want to try some demo that I have listed, let me know in the comments!
