Hi Paul,the erfa package does not migrate because of the bug #1133139 in src:glibc, which creates an errornous liberfa library. Unfortunately, despite being marked as release critical, it is not solved yet. So, there isn't anything I could do here to make it migrating. On the other hand, liberfa is a dependency of astropy and (indirectly) of a large portion of the Astronomy Pure Blend, and it would a pity to see them removed from testing.
