Description

The upgrade path table is missing a lot of options:

https://docs.atlas.mongodb.com/import/mongomirror/#upgrade-path

These are the current valid source/destination versions:

'2.6': ['3.6', '4.0', '4.2', '4.4'],    

'3.0': ['3.6', '4.0', '4.2', '4.4'],    

'3.2': ['3.6', '4.0', '4.2', '4.4'],    

'3.4': ['3.6', '4.0', '4.2', '4.4'],    

'3.6': ['3.6', '4.0', '4.2', '4.4'],    

'4.0': ['3.6', '4.0', '4.2', '4.4'],    

'4.2': ['4.0', '4.2', '4.4'],    

'4.4': ['4.2', '4.4'] 

To perform a downgrade (i.e. 4.0 -> 3.6, 4.2 -> 4.0, and 4.4 -> 4.2) the source must have an FCV that matches the destination.
