fix: import should accept old keys

[betodealmeida]

SUMMARY

#16756 renamed a few fields on a versioned schema, breaking import/export, since old exports are no longer valid.

I reverted the schema to the original V1, and fixed export to produce the original schema. I also fixed the import to support the new keys, since exports might've been made with the incorrect schema.
