Script at the bottom will make this much easier.
The main issue with MongoSync is it doesn’t have the ability to pass the --sslCAFile, at least in 2022 it didn’t, and in fact a lot of methods attempted to do so caused extreme slowdowns or grinded MongoDB 4.4, 5.0, and 6.0 to a halt.
No fix has been implemented, just fyi to help save you from causing a potential outage in your prod environment.
You’re better off setting up a script to sync your DBs in batches via BSON/JSON pushes as it’s safer, and you can script in anything and everything you want and set it up to automatically send the batches, or just listen to changes and send the new files. General template is at the end in the script, the middle script segment can be used to help as well, but that’s what I’d do.
