My main realm was legacy back when export started. Converting it to Pathfinder failed miserably at first. But within the first month or so a big fix came out that let me convert successfully.

I have done exports from it back then as tests of the system. Once the issue with legacy conversions was resolved I've been able to do exports from my main realm and imports into blank realms and into existing realms without any unexpected problems.
