Fields don't survive migration from ss3 to ss4

[OldStarchy]

After upgrading from 3.6.7 to 4.10 the configuration for all the fields in all MemberProfilePages are reset to defaults.
The version of the silverstripe-memberprofiles package was upgraded from 2.0.3 to 4.0.6. Have been following the instructions here.

It looks like all the original field settings have become "archived", though they still all display in the field list. Is there a defined migration strategy for this module?

[OldStarchy]

Some fields are duplicated, all the original fields are still there but have become "archived", and new fields (from the initial dev/build I guess) are duplicating the member fields; there's two "First Name" fields, two "Surname" fields, etc.

[OldStarchy]

I think this is because the fields need to be published initially during migration. Maybe. I need to do more testing.
