    Description

      Created a MongoDB 3.4.15 standalone, then upgraded to 3.6.5, set FCV to "3.6", then upgraded to 4.0.0 rc0. See a message in the log file:

      2018-05-29T12:15:43.124-0500 E STORAGE  [initandlisten] WiredTiger error (-31802) [1527614143:124208][2993:0x7fffddf7a3c0], connection: unsupported WiredTiger file version: this build requires a minimum version of 3, and the file is version 2: WT_ERROR: non-specific WiredTiger error

      but, things seem to be working.

      If WT file version 2 is supported in 4.0, this message should be a warning at most.

      Also, how would one go about converting to version 3, if there is a reason to do so?
