Will the running of the Membership Utility report overwrite manual changes to memberships?

Unless the status has been manually changed, I think the answer is no: a look at the underlying stored procedure (AP_MEMBERSHIP_UPDATE) reveals great attention to changing status (pending to active, active to lapsed, etc.), and nothing else.
As of v12 (I think) this report has a Preview Mode, which you may find useful if you're wondering what the report is going to do when it next runs overnight, for example.
