Migrating from One.com to Theory7: a professional upgrade
Migrating from one.com is a much-discussed topic. One.com advertises with attractive entry prices: hosting from €2.49 per month. What they do not mention prominently is that this price rises considerably after the first year. If you discover this and consider migrating from One.com to another provider, then here you read exactly how that works and what you get in return.
The price problem of One.com
One.com uses a common marketing model: low entry prices to attract customers, followed by considerable price increases at renewal. Below are the current prices, checked in February 2026:
- Beginner package - €2.49 per month in the first year, then €5.99 per month. That is an increase of 140%
- Professional package - €7.49 per month in the first year, then €14.99 per month. That is a doubling of the price
Many customers only realize after a year what their hosting really costs. And by that time switching has become a hurdle, which is why many end up paying more anyway. This is a deliberate strategy and a reason why more and more One.com customers look for a more transparent provider.

Price consistency: no surprises
Migrating from One.com to Theory7 is easier than you think. More and more customers choose to migrate from One.com because of the hidden price increases after the first year.
The biggest difference between One.com and Theory7 is the pricing strategy. At Theory7 you pay the same today as in a year, and in three years. The Mini package is €0.49 per month - now, at renewal and always. There are no introductory discounts that disappear, no hidden price increases and no tricks with contract periods.
At One.com you pay up to 140% more after the first year than the advertised price. The Beginner package rises from €2.49 to €5.99 per month. The Professional package jumps from €7.49 to €14.99 per month. Over five years you pay a total of €359.40 at One.com Beginner, while at Theory7 Starter you pay €173.40 for the same period. That is a difference of more than €185.
The SSH problem
A fundamental difference that is decisive for developers and advanced users: One.com does not offer SSH access. On any package. This means you cannot log in to your hosting account via the command line.
Why is that a problem? SSH access is essential for:
- Git deploys - modern workflows use Git to push code to the server. Without SSH that is not possible
- WP-CLI - managing WordPress via the command line, which is much faster and more efficient than via the web interface
- Composer - PHP dependency management, indispensable for modern PHP projects
- File management - quickly editing files, adjusting permissions or viewing logs without FTP
- Automation - running scripts, setting up cron jobs and automating tasks
- Troubleshooting - viewing error logs directly, testing PHP versions and checking configuration
At Theory7 web hosting SSH access is included by default with every package, including the Mini package of €0.49 per month. This is not a premium feature but a basic provision that every serious hosting provider should offer.
One.com's own panel
One.com uses its own control panel that looks visually attractive, but is limited in practice. The panel is designed for beginners and you notice it: advanced functions are missing or hard to find. For example, you cannot set custom PHP configuration, manage advanced DNS records or create cron jobs via the interface.
Theory7 uses DirectAdmin, a professional and proven control panel that has been developed for more than twenty years. DirectAdmin offers full control over your hosting account: from file management and databases to DNS configuration, email settings and PHP version management. It is user-friendly enough for beginners but powerful enough for professionals.
Speed: NVMe and LiteSpeed
One.com runs on Apache web servers with regular SSD storage. Theory7 uses LiteSpeed Enterprise with NVMe SSD. This sounds like technical jargon, but it translates into concrete advantages:
- NVMe SSD - up to 6 times faster read speeds than regular SSD. This means faster database operations and faster loading of files
- LiteSpeed Enterprise - on average 6 times faster than Apache for dynamic PHP pages. In addition, LiteSpeed has a built-in caching engine (LSCache) that serves WordPress pages in milliseconds
- CloudLinux - guaranteed resources per account, so that other users on the same server cannot slow down your website
The combination of NVMe SSD, LiteSpeed and CloudLinux delivers a noticeably faster website. This is important for your visitors (no one likes to wait), for your SEO (Google rewards fast websites) and for your conversion (every extra second of load time costs revenue).
Security: Imunify vs standard security
In terms of security Theory7 is also ahead of One.com. Theory7 runs Imunify, an advanced security system that works at server level. It automatically detects and blocks malware, brute-force attacks, SQL injection and other threats. Your websites are protected without you having to install security plugins yourself. One.com offers basic security, but lacks the advanced server-side protection that Imunify offers.
In addition, CloudLinux isolates each hosting account in its own environment. This means that a compromised account on the same server cannot affect your website. At One.com this isolation is missing, which poses a potential security risk in a shared hosting environment where hundreds of websites run on the same server.
Email hosting during the migration
An important point of attention when migrating from One.com is your email. If you have email addresses at One.com, these have to be migrated or reconfigured. At Theory7 you can easily create new email accounts with the same addresses via DirectAdmin. If you use IMAP, you can migrate your existing messages by copying them from the old to the new server via an email client.
With our free migration service we also take care of the email migration. We make sure your email accounts are created, that the configuration is correct and that your existing messages are transferred. The MX records are only switched at the very last moment, so that no emails are lost during the transition.
PHP version management and developer tools
In addition to SSH, Theory7 offers even more developer tools that One.com lacks. Via DirectAdmin you can select a different PHP version per domain, from PHP 7.4 to PHP 8.3. This is handy if you manage multiple websites that require different PHP versions. You can also adjust PHP settings via the panel, such as memory limits, upload size and execution time, without having to submit a support ticket.
Other developer features that Theory7 offers by default and One.com lacks:
- Cron jobs - setting up scheduled tasks via DirectAdmin, for example for automatic backups or periodic scripts
- Git integration - via SSH you can use Git repositories for version management and deployment
- Composer - PHP dependency management directly via the command line
- Node.js support - for modern web applications that require Node.js
- Extensive DNS management - full control over A, CNAME, MX, TXT and SRV records
The Website Builder issue
One.com offers its own Website Builder, with which you can build a website without technical knowledge. If you use this builder, you are in fact stuck with One.com - you cannot take your website to another provider, because the builder only works on the One.com platform.
This is a classic vendor lock-in. As long as you stay with One.com, there is no problem. But as soon as you want to migrate, you discover that your website is not exportable. You have to rebuild the site at another provider or in another system.
The solution? Use an open platform such as WordPress. WordPress is free, open source and runs on every hosting provider. You can migrate your WordPress website to another provider at any time - there is no lock-in. At Theory7 WordPress is optimized with LiteSpeed and the LSCache plugin for maximum speed.

Step by step: migrating from One.com to Theory7
The migration depends on what type of website you have at One.com.
Migrating a WordPress website
Do you have a WordPress website at One.com? Then the migration is easiest:
- Order a Theory7 package - choose your package on the web hosting page
- Request free migration - open a ticket with your One.com login details and our team arranges the rest. More information on our migration service page
- Or do it yourself - install the All-in-One WP Migration plugin on your One.com WordPress, export your site and import the file on your new Theory7 account
- Test everything - check your website via the hosts file before you change DNS
- Change DNS - point your domain to Theory7
Migrating a Website Builder site
Anyone who wants to migrate from One.com quickly notices that the switch goes smoothly. Migrating from One.com is a logical step if you are no longer willing to pay double after the first year.
Do you use the One.com Website Builder? Then a direct migration is unfortunately not possible. Your options:
- Rebuild in WordPress - choose a WordPress theme that resembles your current site and recreate the pages. This takes time, but afterwards you have a flexible website that you can host anywhere
- Copy the content - you can take the texts and images of your current site with you. Save everything and use it as a basis for your new WordPress site
Migrating a static website or custom code
- Download your files - use FTP to download all files from your One.com account
- Export databases - if you use a database, export it via phpMyAdmin
- Upload to Theory7 - upload files via SFTP and import the database
- Test and switch DNS
Taking your domain with you
If your domain is registered at One.com, you can leave it there and only change the DNS. You can also transfer the domain: request a transfer code from One.com and start the transfer to Theory7. Note: One.com can take up to 5 working days to provide a transfer code. So plan this well in advance.
Dutch support and guidance
One.com is a Danish company that does have a Dutch-language website, but the quality of the support is rated variably. At Theory7 you get Dutch-language support via phone, email and the ticket system. With technical problems or questions about the migration we help you directly. We also offer an extensive knowledge base with guides for common tasks, from WordPress installation to DNS configuration and email settings. Personal, fast support in your own language makes a big difference, especially when your website unexpectedly has problems.
