I would like to ask, is it safe to migrate from 3.1.1 to 3.7.0? Is it better gradually, for example 3.1.1 -> 3.2 -> … -> 3.6 -> 3.7?
RC will apply all database migrations step for step. So it should be safe to jump to 3.7.0. If you use mongodb >= 4, you should probably stay at 3.6.3 until another problem is fixed.
Are you talking about the CPU problem?
Yes, this should be fixed soon I think.
Thank you very much :).
