How much does Mattermost cost?

How hard is it to migrate off Mattermost?
It depends on history, integrations and headcount far more than on the tool itself. For a team of 50 with a handful of integrations, expect a few weeks of elapsed time and one to two weeks of actual work. Above 200 people, or with compliance in scope, plan a quarter.
