I am preparing my ZCM 11.4.3 system to migrate to ZCM 2017 and while doing my backup steps I noticed that my zen_audit_[zone].log and zenworks_[zone].log files are 16 and 9 GB respectively. Is there something that can be run to reduce the size of these logs or are they safe to stop sybase services, move, then restart services and have them get recreated?
