You should migrate if: your Kentico site is slow, your hosting costs are climbing, you need developer flexibility, or you want to adopt a modern JAMstack architecture.
You might want to stay if: your Kentico site benefits from integrated marketing automation, email, and a/b testing and you don't have JavaScript/TypeScript developers on your team.
The migration itself is straightforward with LeaveWP — enter your Kentico URL, select SvelteKit, and download your content. The more important question is whether SvelteKit's architecture fits your team's skills and your project's long-term needs.
