I plan to upgrade the XR12K PCMCIA flash card from 1GB to 4GB, and same time upgrade IOX from 3.6.2 to 3.9.1.
How to backup the configuration and restore backup the configuration during upgrade ?
I knew IOX store the configuration files in /config directory of Disk0:
Can the copy command work ?
eg. copy running config to bootflash, then upgrade PCMCIA flash, after IOX booted, then copy back the config.
RP/0/0/CPU0:router#copy running-config bootflash:
Destination file name (control-c to abort): [/running-config]?
Directory of bootflash:
1 -rwx 3555908 Sat Jan 1 08:40:56 2000 c12kprp-boot-mz.120-32.S3.bin
3 -rwx 20887 Tue Jul 20 14:32:40 2010 running-config
66322432 bytes total (62724364 bytes free)
After the new IOX booted from new PCMCIA flash with default config, then copy the backup config at bootflash: back to running.
RP/0/0/CPU0:router# copy bootflash:running-config running-config
Yes the copy command will work here also you can copy the running config to bootflash and than take it back to running.
But better to follow following process
1. Take out the running config to tftp server
copy running-config #tftp://22.214.171.124/auto/tftpboot-projects/prgoel/
2. once u move it to new release ( 391) , check that u have server reachability ( check mgmt has ip and have static route )
3. than move to config t
and try load tftp://126.96.36.199/auto/tftpboot-projects/prgoel/
and than on config mode commit
If you donot have tftp server , than u can copy it in bootflash , but load the config and than do commit.
