There are some circumstances where the newer MongoDB 4.2 FCV 4.2 Ops Manager backups may not be desired by the customer.
When deploying a new MongoDB 4.2.x instance the data files are created by default using FCV 4.2.
Currently the best and cleanest way to run MongoDB 4.2.x FCV 4.0 data files when deploying a new instance is:
- start MongoDB 4.0.x
- allow it to generate the data files
- finally upgrade it to MongoDB 4.2.x.
It would be nice to have a way to configure MongoDB to create FCV 4.0 data files at startup.
