Description
Description
Based on https://docs.mongodb.com/manual/tutorial/restore-sharded-cluster/.
Since the step includes dropping the local database of the config server (in effect, the oplog), it should also delete the _id: minOpTimeRecovery document in admin.system.version of every shard.
If the user decides to ever change the shardNames after restore, they would also need to drop config.cache.collections, config.cache.chunks.* (for v3.6 or greater) and drop config.cache.databases (for v4.0 or greater) in every shard.
Scope of changes
- (Pending feedback from engineering) add step for removing minOptimeRecovery document
- Add steps for removing various *.cache collections on shrad name change
