We need to do a upgrade from mongoDB 4.0 to mongoDB 4.4.
( the 4.2 version have a big problem with backup PIT ).
We want to perform a mongodump on one database ( using the 100.5.1 version ) under mongoDB 4.0 and perform a mongorestore ( using also the 100.5.1 version ) of the database under a mongoDB 4.4 version.
The mongo support wrote that it is possible but not really supported.
May you help us to understand what is supported and what is not supported using this method od backup/restore.
It is important for us to have a support for this procedure.
