This artical will introduct how to migration IOS XR 32-bit(cXR) to IOS XR 64-bit(eXR) and how to rolling back from eXR to cXR.

cXR to eXR by use eUSB
eUSB means Emabedded Universal serial bus, According to my idea is the existence of harddisk: or harddiskb: on 9K

eXR to cXR downgrade
You will only need to use below command:
1 2 3 4 5 | copy tftp://10.75.49.254;MGMT/IOX533/asr9k-mini-px.vm-5.3.3 harddiskb: <<< befor 6.1.4 you need copy vm file to harddiskb, then copy it from harddiskb: to harddisk: copy harddiskb:/asr9k-mini-px.vm-5.3.3 harddisk: <<< after 6.1.4, you can copy vm file to harddisk directly admin copy harddisk:/asr9k-mini-px.vm-5.3.3 location 0/RP0/CPU0/VM1 harddiskb:/ run /etc/rc.d/init.d/migrate_to_cXR -b eusb -m rp0 -r <<< (router will reload) |
