If you think TYPO3 v13 is just another routine update, think twice! This upgrade modifies how agencies deliver/manage and futureise client projects with a faster editing experience built on a cleaner and modern technical foundation.

As the latest Long Term Support (LTS) version, TYPO3 v13 is about providing agencies with a more solid, safe, and scalable CMS. The choices you make now, whether you are running multiple client sites or one large client platform, will determine whether your experience in the next few years is smooth or a hassle.
*In this guide, we’ll cover what’s new, what’s changing, and how agencies can prepare!*
TYPO3 13 introduces several helpful updates and system enhancements that agencies will notice immediately. The focus is on speed, usability, and cleaner coding, which ultimately improves project readiness and maintainability.
#### **1. A smoother backend for editors**
The [**TYPO3 backend**](https://nitsantech.de/en/blog/typo3-backend) has been redesigned to be faster and easier to navigate. The work of editors has been made significantly more efficient through mass editing features, a modernized page tree, and the choice between dark mode and light mode.
#### **2. Modern technology under the hood**
[**TYPO3 v13 updates**](https://nitsantech.de/en/blog/typo3-v13-roadmap-announcement) the core to modern frameworks and removes outdated code that previously slowed down the system. It has been switched to PHP 8.2 or higher, which provides [**TYPO3 performance**](https://nitsantech.de/en/blog/typo3-performance-optimization) improvements and ensures long-term security.
#### **3. Improved localization and media handling**
The tools around localization and translation offer optimized workflows for global projects. [**TYPO3**](https://nitsantech.de/en/blog/typo3) improves the handling of modern image formats like WebP to increase user-friendliness and offers intelligent image cropping, allowing editors to work more flexibly without additional plugins.
#### **4. Stronger security and reliability**
Security throughout the system and in the extensions has been improved. The innovations in TYPO3 13 make it easier for developers to meet modern security requirements and best practices. Thanks to new coding standards and updated libraries, the system is now more stable and secure than ever before.

For agencies, TYPO3 13 presents a major opportunity. All major TYPO3 version releases shift how projects are developed and supported. Understanding those shifts can help TYPO3 agencies stay ahead of competitors and ease any last-minute panic over having to migrate TYPO3 versions.
#### **1. It influences project timelines and budgets**
As old APIs are removed and new system requirements are introduced, updates may require more time for testing and implementation. TYPO3 agencies that start planning early can better schedule and implement updates, rather than reacting only when a client deadline is pressing.
#### **2. It improves how teams work**
The faster backend, optimized code, and modernized tools reduce friction points in the daily workflow for both developers and editors. TYPO3 projects can be launched faster, maintenance becomes easier and more efficient, and teams work more productively and contentedly.
#### **3. It protects client relationships**
The use of unsupported [**TYPO3 versions**](https://nitsantech.de/en/blog/check-typo3-version) increases security risks and maintenance efforts. Agencies that systematically migrate their clients to TYPO3 13 gain trust and demonstrate a willingness for long-term partnership, an important advantage in a competitive market.
#### **4. It opens new revenue opportunities**
Each upgrade offers the opportunity to create additional value. Agencies can provide migration projects, extended maintenance packages, or training on new workflows. Performance audits are also worthwhile. The [TYPO3 v13 upgrade](https://nitsantech.de/en/blog/typo3-update-upgrade) provides the chance to deepen customer relationships and open new avenues for digital growth.
TYPO3 13 introduces some technical details for agencies to know prior to upgrading. These changes improve performance, security and maintainability but might impact older projects.
##### **1. PHP and Database Requirements**
- TYPO3 13 requires PHP 8.2 or higher, otherwise an error will occur.
- TYPO3 13 supports the following databases: MySQL 8.0.17+, MariaDB 10.4.3+, PostgreSQL 10+, and SQLite 3.8.3+.
##### **2. Removal of Deprecated and Legacy APIs**
- All classes and methods marked as deprecated in version 12 have been removed. Code based on these may therefore fail.
- The methods within GraphicalFunctions have been removed in version 13. Image generation is now done via GifBuilder.
- In the TypoScript context, some elements have been removed without direct replacement options.
##### **3. Extension Compatibility**
- Some third-party extensions may not work immediately. Agencies should therefore check compatibility with tools like the [**TYPO3 Extension**](https://nitsantech.de/en/blog/typo3-extensions) Upgrade Checker Tool.
- Extensions may need to be updated or replaced before migration.
##### **4. Configuration and Setup Changes**
- TYPO3 13 has added new configuration guidelines and removed deprecated ones.
- Server environments must meet the new system requirements to ensure stability.
##### **5. Backend and User Interface Enhancements**
- The backend now features more intuitive operation, faster loading times in the page tree, mass editing, and support for right-to-left languages to improve localization.
##### **6. Testing and Migration Tools**
- The official documentation contains steps for dealing with breaking changes and extension updates.
- Agencies should first use the compatibility tool to check installed extensions before upgrading.
These changes make TYPO3 13 faster, cleaner, and more secure, but careful planning and testing are essential for a smooth migration.
Preparing for TYPO3 v13 will make sure that your agency is able to successfully upgrade sites for your clients without unnecessary downtime and errors.
Here is a working [**TYPO3 Roadmap**](https://nitsantech.de/en/blog/typo3-roadmap) to prepare:
##### **1. Audit existing installations and extensions**
- Create a list of all client websites, individual modules, and third-party extensions.
- Analyze which of them are compatible with TYPO3 13 and decide whether updates or replacement solutions are necessary.
##### **2. Set up a staging environment**
- Perform all upgrades in a staging environment first before making changes to live websites.
- Use this environment for regression tests, content checks, and performance analyses.
##### **3. Plan budgets and timelines**
- Create initial effort estimates for each website, including necessary extension updates and testing times.
- Plan buffers for unexpected tasks so that your projects do not stall.
##### **4. Communicate with clients**
- Proactively inform your clients about upcoming changes, planned maintenance times, and the benefits of the upgrade.
- Offer upgrade packages, maintenance options, or staggered migration plans to make costs transparent for clients.
##### **5. Train developers and editors**
- Developers need to familiarize themselves with the removed APIs and new features.
- Editors need guidance on new backend tools, such as mass editing or handling images.
##### **6. Implement monitoring and fallback strategies**
- Create backups before performing the upgrade.
- Plan fallback strategies in case issues arise during the migration to TYPO3 v13.
- Monitor performance metrics and error logs after the upgrade to ensure stability.

How long will TYPO3 12 be supported?
The support for TYPO3 12 LTS is provided up to April 30, 2025, for bugs and until October 31, 2025, for security issues. Sites should be upgraded before the support period lapses to maintain their security.
How much does a TYPO3 13 upgrade cost?
Costs vary for different sites based on their size, complexity, and the installed extensions. Each project will need to be reviewed in order for us to generate a realistic cost estimate.
Will my existing extensions work with TYPO3 13?
Not all extensions may be compatible from the start. It's important to check for compatibility when upgrading and find replacements for extensions you are using that rely on deprecated APIs.
How long does a typical upgrade take?
The time can vary depending on the number of sites, extensions, and the amount of customizations. A simple and small website might take a few hours to a day, while larger or complicated sites may take several days.
