Are you aware of anything that describes how to upgrade SOGo from 0.9.7/SOGO 3.2.10 to 0.9.8/SOGo 4.0.0.
It is as simple as dump the db and restore it on to a new instance?

Rather than upgrade in place we spin up a new instance and migrate the data so we can test before placing the new VM into production. The piece I am missing is SOGo.

I have not had any luck searching your documentation page or with google.
