Hey,

I have some concern regarding mongify I hope you can help me in this regard, just I need some clarification on the below mentioned questions:
1 . How to ensure the data is not corrupted while migrating ?
2. data types conversion from sql to mongo
3 . Check what permissions are required for Mongify to work ?For example, the environment in the Bank is restricted
4 . What is “check” doing ? (Mean it only checks the connection or checks the schema also)
5 . How is Mongify working ? What is the mechanism ?
6 . Constraints – if any for mongify – like linux / ubuntu / versions.

Kindly help me
Thanks in advance
