I have a MongoDB database running on a headless Raspberry Pi 3 which runs 32-bit Raspbian and MongoDB v2.4. I also have MongoDB running on my Mac, with 64-bit Big Sur and MongoDB v5.0.

I have data that I'd like to move from my Pi to my Mac. How could I accomplish this? Would it even be compatible?

In MongoDB v2, there's db.copyDatabase() which has since been deprecated since v4. In MongoDB v4, there's mongodump, but that's incompatible with v2.

in your raspberrypi dupm your db with:

mongodump --db=dbname --out=./

and send it to mac and on your mac restore it by :

mongorestore -d dbname -c collectionName  /place_of_dumpfile --drop 

do it for each collection , or

 mongorestore -d dbname   /place_of_dumpfile --drop
