How to move configuration from VRP3.1 to VRP5.1

Publication Date:  2012-07-27 Views:  36 Downloads:  0
Issue Description
After upgrading software from software version VRP3.1-2317 to VRP5.1-0211 all configuration were lost.
Hardware: NE40-4
Software: VRP3.1-2317, VRP5.1-0211
Alarm Information
"CFM_ReadFlash failed"
Handling Process
Configuration file cant be inherited by new software so you need to move it manually.
To move configuration from VRP3.1 to VRP5.1:
1. backup configuration file
2. VRP3.1 and VRP5.1 are completely different, so prepare analogy configuration for new software step by step
3. upgrade software
4. input configuration step by step through terminal manually
5. save configuration
Root Cause
Both version use vrpcfg.zip file to save configuration, but after software upgrade vrpcfg.zip became unreadable by VRP5.1.
I have checked flash by reading\writing from\to flash and it’s work without faults.
Suggestions
Null
