Migrator for Notes to Exchange - Console/ logged on session / log out cancels migration

When running large migrations with Migrator for Notes to Exchange we utilize win2016 workstations - these workstations have a GPO (business forced) to log out a user session when there is no activity

= contradictory as the NME console is actively running a migration in the background. When the user session logs off - the migration stops.

= its more political than anything - but I cannot find in the documentation where is recommends/states that GPO's or user session time out limitations will impact migrations. 

Is there any documentation to  support what I am experiencing?  I need certain vendor documentation that advises against such settings to allow for un-interrupted migrations  

I am not referring to the SSDM Scheduling Administration / scheduled tasks.
