Regarding Mongify

[MOHAMMAD-FATHA]

@anlek Hey I have some doubts and issue with mongify can you please help me to resolve it, I request you to go through 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.

And also I have error while using sync command the error as mentioned below
