Should You Switch from WordPress to microCMS? An Explanation of Decision-Making Criteria, Pros and Cons, and Specific Steps

Hello. This isKototsuki Design.

To those of you currently running a website on WordPress: “The site seems to be getting a little slower,” or “Every time I see security news, I worry whether we’re really safe.” When I consult with clients in Shiga about their websites, I often hear these kinds of “minor concerns” from people who are already using WordPress.

First, let me share my honest conclusion as a professional. In short, migrating from WordPress to microCMS is “unnecessary” for most companies. There’s no need to force a fundamental change to a system you’re already comfortable with.

However, if you’re hitting a wall with page load speeds, want to overhaul your security architecture, or aim to streamline your operational workflows—and any of these apply to you—then migrating to microCMS will be an excellent investment.

In this post, I’ll lay everything out on the table—from a “YES/NO Score Assessment” for those on the fence about migrating to the actual “costs, timeline, and detailed steps.” If you’re wondering, “What exactly is microCMS?” be sure to check out this microCMS overview article as well.

Should You Migrate? “1-Minute Score Assessment”

This is a self-assessment to help you decide “what’s best for our company.” Count how many items apply to you.

◯ Items to Consider for Migration (1 point per item)

• □ Pages take more than 3 seconds to load, and you’re concerned about customer drop-off
• □ You haven’t updated plugins or the core software for over six months, and this makes you uneasy
• □ You want to pursue a more flexible, high-quality design that isn’t dependent on specific templates
• □ You update content frequently, and the sluggish admin interface is causing stress
• □ There were signs of external attacks (such as login attempts)
• □ You’d rather spend your time creating and publishing content than maintaining the site

Diagnosis Results

• 1–2 points: No changes needed. Continue using your
  current website. With the right settings, it can still be improved.
• 3–4 points: Time
  to consider improvements or migration Your current system is beginning to reach its limits. We recommend either partial upgrades or considering a migration.
• 5 points or more: Migration recommended
  . By migrating to microCMS, you’ll achieve surprisingly streamlined and secure operations.

Conversely, you don’t need to migrate if you fit these criteria

Even if your score is high, continuing to use WordPress might be the right choice if any of the following apply to you:

• Low update frequency: You update only a few times
  a month and have no major complaints about your current setup.
• You have no issues with site speed

  You don’t feel stressed by your site’s loading speed.

• Cost is
  a priority You want to keep costs as low as possible and easily change the design.
• You want to
  handle everything in-house You want to add features—such as plugins—on your own without specialized knowledge.

The Difference Between WordPress and microCMS

Let’s compare how each system works by using buildings as an analogy.

Estimates for “Cost” and “Timeframe”

Here are actual estimates forKototsuki Designregarding the questions, “How much will it cost, and when will it be finished?”

• Small-scale site (a few pages): Approximately 400,000–600,000 yen
• Medium-sized sites (including content migration): Approximately 800,000 to 1,500,000 yen
• Large-scale, high-functionality sites: 1.5 million yen and up

Production Time: Approximately 2 to 6 months

We don’t simply transfer data.

Just as when “building a new house,” we prioritize creating a “user-friendly” experience that allows you to continue publishing content stress-free for years to come.

Key Migration Steps (6 Phases)

Migrating a website is similar to building a house. You lay a solid
foundation, erect the pillars, and create a comfortable living space. In website development, we proceed carefully as follows:

① Diagnosis and Inventory of the Current State (Site Survey)

First, we thoroughly review all the content on your current WordPress site.

Sorting Articles

Which of the past posts should really be migrated? We organize unnecessary information to streamline the site.

Understanding the Structure

We’ll visualize the information that makes up the current site—including categories, tags, and custom fields.

② Content Redesign (Blueprint)

microCMS does not have a “body text field” by default.

Schema Design

We’ll define each field—such as “Title,” “Body,” “Photo,” and “Post Date”—one by one.

Customizing the Admin Interface

At this stage, we design a “dedicated posting screen” to ensure contributors don’t get lost. This is the core component that determines the future user experience.

③ Environment Setup (Foundation Work)

Based on the design blueprint, we’ll create the data interface (API).

API Implementation

We implement the designed fields within microCMS.

Permissions and Security Configuration

We’ll reinforce backend security by defining the scope of access for each editor and configuring preview settings.

④ Front-End Development (Framework Setup)

At this stage, we build the new “front-end interface” that customers will see.

Implementation of the Latest Technologies

Using technologies such as Next.js, we write code to ensure pages load instantly.

Design Refinement

We fine-tune the user experience—such as readability on smartphones and the ease of pressing buttons—to ensure a polished feel.

⑤ Data Migration

Engineers will use specialized programs to carefully migrate the data.

Creating a Conversion Program

We’ll convert WordPress data into a format that microCMS can understand and import it in bulk. Since this isn’t a manual process, we can accurately migrate even several thousand entries.

Image Optimization

Photos are transferred to the microCMS server and converted to next-generation formats (such as WebP) for faster loading.

⑥ Final Testing and Launch (Completion)

Redirect Configuration (Important)

This is the lifeline of SEO. We carefully configure redirects to ensure search engine rankings are carried over from the old WordPress URLs to the new ones.

Functionality Testing

Common “Failure” Scenarios in microCMS Migrations

We’ll also be honest about cases where things don’t go as planned.

• Deciding
  Based Solely on “Trends” Content contributors may struggle to adapt to the new system, causing content publication to grind to a halt.
• Lack
  of an Engineer Even if you want to make major design changes on your own after launch, you won’t be able to do so if you can’t write code.

If you want to “handle everything on your own and continue customizing easily,” WordPress might be the better choice for you.

Summary: For Those Who Are Undecided

WordPress or microCMS?
This isn’t a question of “which is better,” but rather “which one gives you the most freedom right now.”

For most companies, the status quo is sufficient. However, for those with the ambition to “build even more trust” or “deliver an authentic brand experience,” microCMS will be a strong ally supporting that future.

If you’re having trouble deciding which one is right for your company, let’s start by assessing the current state of your website together. Whether you’ve found issues using an SEO diagnostic tool or not, please feel free to contact us.
