Symptom
- The attempt to downgrade a Palo Alto Networks Firewall from PAN-OS version 10.1.X to 10.0.X version fails due the following error "request mongo set storage-engine instance corr format mmap"
Environment
- PA-3250
- PAN-OS version: 10.1.5 downgrade to 10.0.0 version
Cause
CDB Downgrade from 10.1 to 10.0
- Since PAN-OS 10.0 only supports MMAP for CDB instance, downgrade from 10.1 to 10.0 is blocked based on the current Storage Engine
- If WT is the storage engine for CDB in PAN-OS 10.1, then downgrade is blocked and a warning is presented
Resolution
