Migrating from Mijndomein to Theory7: more value for less
Are you considering migrating from Mijndomein to another hosting provider? Mijndomein is a well-known name in the Dutch hosting market, but when comparing specifications and prices, many website managers discover that there are alternatives that offer more for less money. In this article we objectively compare the current plans of Mijndomein with Theory7, look at where the differences lie and explain how the Mijndomein migration process works step by step.
Why website managers consider migrating from Mijndomein
Mijndomein, part of the team.blue group, offers web hosting with NVMe SSD technology and a user-friendly interface. They are known for their simple onboarding process and transparent basic prices. Yet customers sometimes look for alternatives because of the following considerations:
- Limited storage space with entry-level plans - the Web Hosting Start plan (€4.50/mo) offers 1 GB of disk space, which is quickly too little for modern websites with media files. The Plus plan (€8.50/mo) offers 20 GB.
- A limited number of databases - Start offers 1 database, Plus offers 10. For those who want to host multiple WordPress sites on one account this can be limiting.
- No LiteSpeed technology - although Mijndomein uses NVMe SSD, the hosting does not use LiteSpeed web servers, which can deliver a significant speed gain for dynamic websites.
- Price per unit of storage - when comparing what you get per euro, it stands out that newer providers sometimes offer considerably more storage capacity for comparable money.
- Scalability - for entrepreneurs with multiple websites, every extra project may mean a separate plan at Mijndomein, which drives up costs.
Mijndomein offers solid hosting with good support and reliable uptime. Still, it pays to compare the options if you are looking for more value for your money. Also read our article about hosting costs in 2026 for a market-wide overview.
An honest comparison: Mijndomein versus Theory7
Let's put the current plans side by side. It is important to look at comparable price categories. Mijndomein offers Web Hosting Start for €4.50/mo (after the introductory period) and Web Hosting Plus for €8.50/mo. Theory7's Basic plan costs €4.99/mo. Here is an objective comparison:
| Feature | Mijndomein Start (€4.50/mo) | Theory7 Basic (€4.99/mo) | Mijndomein Plus (€8.50/mo) |
|---|---|---|---|
| Price per month | €4.50 | €4.99 | €8.50 |
| SSD storage | 1 GB | 250 GB | 20 GB |
| Number of databases | 1 | Unlimited | 10 |
| Number of websites | 1 | 25 websites | 1 |
| Web server | NVMe SSD platform | LiteSpeed Enterprise | NVMe SSD platform |
| Redis caching | Not stated | Included as standard | Not stated |
| Free SSL | Yes | Yes | Yes |
| Email accounts | Unlimited | Unlimited | Unlimited |
| Backups | Yes | Daily (14 days) | Yes |
| Bandwidth | Unlimited | Unlimited | Unlimited |
| Control panel | Plesk | User-friendly panel | Plesk |
| Dutch support | Yes | Yes (a personal team) | Yes |
What stands out: Mijndomein Start is €0.49 per month cheaper than Theory7 Basic, but offers 250 times less storage (1 GB versus 250 GB) and only 1 database versus unlimited. Mijndomein Plus costs €3.51 more per month than Theory7 but still offers only 20 GB storage versus 250 GB, and limits you to 10 databases versus unlimited at Theory7.
If you have a simple website that needs little space, Mijndomein Start can be sufficient. For growing websites, multiple projects or WordPress sites with media, however, the price-performance ratio at Theory7 is considerably better.
Where Theory7 makes the difference
When considering migrating from Mijndomein to Theory7, these are the concrete advantages:
LiteSpeed Enterprise for faster websites
Theory7 runs on LiteSpeed Enterprise web servers, the fastest commercially available web server technology. Combined with Redis object caching, dynamic websites such as WordPress load up to 40-60% faster than on traditional platforms. This is measurable in PageSpeed tools and has a direct impact on user experience and SEO. Want to know more? Read our article about improving website speed.
250 GB storage for €4.99 versus 1 GB or 20 GB
The storage difference is substantial. For €4.99 per month you get 250 GB SSD at Theory7, which is 250 times more than Mijndomein Start (€4.50) and 12.5 times more than Mijndomein Plus (€8.50). This means room for extensive media libraries, multiple WordPress installations and growth without worrying about limits.
Unlimited databases and 25 websites per account
Theory7 lets you host 25 websites with unlimited databases on one Basic plan. With Mijndomein Start you have 1 database, with Plus 10 databases, and both limit you to 1 website per plan. For web designers, freelancers or entrepreneurs with multiple projects this is a big difference in both flexibility and cost.
Transparent prices and modern technology
Theory7 combines modern web server technology (LiteSpeed, Redis) with clear prices without hidden costs. What you see is what you get, with no upsells for basic functionality.
How does migrating from Mijndomein to Theory7 work?
The migration process is simple. Theory7 offers a professional SiteSwitch migration service (normally €59.95, free with Basic+ and higher plans) in which experts move your website without downtime. The process in four steps:
Step 1: order your Theory7 plan
Go to the Theory7 Mijndomein migration page and choose the plan that suits you. For most websites the Basic plan (€4.99/mo) is more than sufficient with 250 GB SSD and all premium features.
Step 2: share your Mijndomein access
After your order you receive instructions by email. You securely share your Mijndomein Plesk login or FTP details and database access with the migration team. These details are used solely for the migration and deleted afterwards.
Step 3: Theory7 migrates your website
The technical team copies your complete website: files, databases, email accounts and configuration. This happens while your website stays online at Mijndomein, so there is no downtime. Everything is checked before you get the green light.
Step 4: change DNS and go live
As soon as the migration is complete, you change the DNS settings of your domain to Theory7. Within a few hours your website runs on the faster servers. Consult our domain name migration guide if you also want to transfer your domain.

Cost savings with multiple websites
The difference becomes extra clear when you manage multiple websites:
| Scenario | Mijndomein (per year) | Theory7 (per year) | Difference |
|---|---|---|---|
| 1 website, basic plan | €54 (Start) | €59.88 (Basic) | -€5.88 |
| 1 website, Plus plan | €102 (Plus) | €59.88 (Basic) | +€42.12 saving |

- Keep both accounts active temporarily - only cancel Mijndomein after everything works correctly at Theory7. Keep at least one week of overlap.
- Test all functionality - check pages, forms, online store functions and email thoroughly on the new server before you switch over definitively.
- Lower the DNS TTL in advance - set your DNS TTL to 300 seconds a day before the migration for faster propagation.
