I’m updating a 3.6.1 mongoDb server and the goal is to arrive to use the latest version (4.4.1).
I did create a server copy in order to experiment without fear to disrupt any service.
In that server I successfully updated from 3.6.1 to 3.6.20 and then from 3.6.20 to 4.0.20.
Do I have to escalate version by version or I can jump to the 4.4.1 ?
On some early tests trying to migrate to a 4.2.10 I did experience the error 14.
I did find lot of info and suggestions to fix the error 14 but nothing worked for me so far, so I erased the server and restored to 3.6.1 and then re-upgraded back to 4.0.20.
So I wonder what would be the best strategy to upgrade it.
