My eldest child was mix fed and we regularly alternated between 2-3 different formula brands, including when we traveled overseas. We just did a direct switch, no transition and no issues. Formula in Australia is very well regulated so basically formula composition needs to follow a similar recipe and most babies should have no issues when switching from one to another.
