I was in a similar position, but highly motivated to switch due to advancing RSI symptoms. I waited to switch until a low-code, long-duration project came across my desk and was pleasantly surprised by how quickly my old habits were replaced. The trick seems to be that with split keyboards (especially orthilinear models) the finger closest to the next key is usually the one you ought to use anyhow. When home-row is mandatory, it's easy.

After a month or so at most, I was back to full speed. It did ruin me for laptop keyboards, though, I can't type on those at all anymore.

Similar experience, except I was surprised to find that my laptop typing have actually been improving without trying despite (or due to?) also using a qwerty but otherwise quite different layout.
