Migrating a website from Sanity.io to WordPress Headless. Do you have any experience with that?

One of the prospective clients I'm talking with is currently using [Sanity.io](https://Sanity.io) Headless CMS for their mid-size website and wants to migrate to WordPress (preferably WordPress Headless).

I searched for experiences with this, but the results are the reverse: Moving from WordPress to Sanity. That makes sense, as Sanity is pretty new and is built around that expectation.

I asked the client why they were planning this move. They said they were pretty smitten with it when they started a few years ago, and they have grown with it. But they also see it as impeding their future growth and success. It's getting more complex to maintain, build new features, and train their non-technical staff to use them. Plus, not many are familiar with its unique quirks. Cost is also one more reason.

Why WordPress specifically (and not Prismic or any other CMS)? WordPress is FOSS and has big community support, especially in their industry (Digital Publishing). That's good enough for them to build a solid base on for future growth.

We have experience migrating from other old/proprietary CMS to WordPress, but this request is a bit surprising. Do you have any experience with it? Please share if you do.
