Craft CMS major version upgrades

# Still on Craft 4? Let’s get you upgraded.

Craft 5 is out, it’s stable, and it’s significantly better. But upgrading between major versions carries real risk if you don’t know what you’re doing, I do. I’ll handle it so you don’t have to worry.

## What's Actually Involved in a Craft 5 Upgrade?

A major version upgrade is more than running a single command. A thorough upgrade involves auditing your current plugin set for Craft 5 compatibility, identifying and replacing plugins that haven’t been updated, testing the upgrade on a local copy before touching your live site, handling any custom field type or content model changes, updating custom modules and templates, and deploying to production with a rollback plan in place.

Skip any of those steps and you risk a broken live site, data loss, or silent content corruption that you might not catch for weeks.

## Why Not Just Do It Myself?

I’ve handled this process dozens of times. I know which plugins break on upgrade, which content field types need special treatment, and how to keep your live site running throughout. The goal is zero surprises.

> Seth’s support is always quick, clear and practical, and he genuinely takes the time to understand what we’re trying to achieve rather than treating it as just another development job.
> 
> We rely on him for ongoing website maintenance, and whenever something needs updating, fixing or improving, we know it will be handled quickly and properly.

## What It Costs

Pricing depends on the complexity of your site, primarily the number of plugins, any custom modules, and the size of your content model. For most sites, a Craft 5 upgrade is a fixed-price project. Get in touch and I can usually give you a realistic ballpark within 24 hours.
