I have try .gz file to upgrade the Junos. But I cannot upgrade with this extension file. How can I try the Junos with .gz file extension? We can upgrade successfully the Junos with .tgz extension. Is there any convertor software need to convert this extension?
The files with .gz extension are basically recovery software packages that you can use to recover primary compact flash drive i.e. Re-format the RE. These are the install-media you find on download section.
To use the .gz files, you need to a USB which is made bootable using the 'dd' command using the .gz file and this basically returns the device to factory default state.
Thanks for your reply. But I don't understand what do you mean. Please can you share me the documentation or the technical blog to proceed this upgrade process. Can I upgrade the MX router with .gz file directly?
