For us at Doctave (https://www.doctave.com), migrating customers from existing solutions manually ourselves has proved very effective.

The product is a technical documentation platform, and most customers are coming from an existing solution - be it an open source static site generator or CMS of some sort. The pain of migrating is usually a big factor keeping teams in their existing setup, and doing the migration for them eliminates a common objection.

We'll likely keep doing this even as we grow, but right now we tend to offer this service regardless of the size of the customer. The combination of great customer service and everything we learn while migrating the existing content makes it worthwhile.
