      1. Make the config server require, in FCV 4.4, the ChunkType sent in commitChunkMigration to include a chunk version.

      2. Make the donor send the chunk version as of the start of the migration in commitChunkMigration, and if commitChunkMigration exhausts network retries, retry _configsvrEnsureChunkVersionIsGreaterThan with the same chunk version until hearing success before refreshing to find out if the migration committed.
