Almost every successful medium- or large-sized company has done this. As they grow, they open new offices, which they seed with existing staff who are willing to either permanently or temporarily relocate. Most of the time those offices have specific areas of focus, at least when they're starting out. That way they minimize cross-geographic dependencies. To pick a totally non-random example, Stripe has followed this model. It's evident when one looks at their job listings: https://stripe.com/jobs/search

By growing any one of their regional offices, they could move their headquarters. Toyota recently did this over the course of several years. They announced the relocation in 2014, but didn't officially move the HQ until 2016. The planning and execution spanned years before and after that timeframe as well.
