    Description

      Currently, we are unable to resume a change stream on the recipient after a large (>16mb) transaction is committed on the Donor. When attempting to resume the change stream on the Recipient, we get a ChangeStreamHistoryLost error. We should ensure that this works properly for transactions committed before the migration, and those committed during oplog catchup.

      Also, we'll want to remove tenant_migration_recipient_shard_merge_copies_change_collections.js from the the exclude_files list in replica_sets_large_txns_format.yml
