https://community.extremenetworks.com/t5/extremeswitching-eos/upgrading-x460-48t-to-5520-48t/m-p/56459#M810 Hello All (first post!) -&nbsp;<BR /><BR />Apologies, but I'm fairly new at this. I inherited a pair of X460s that are going EOSL and we're looking to replace them with a pair of 5520s. The pair is configured as a 'stack' and are the core switches at our datacenter. These 460s are pretty old and wondering if I can just restore the config to the 5520s? I imaging the XOS is quite a bit different. I was able to TFTP the primary config for backup.&nbsp;<BR /><BR />My plan would be to turn the 5520s on, let them pull a dhcp address and then upgrade the firmware first. From there, not sure if there is more I need to do before restoring the config - but I know I want to avoid an IP conflict, so just wondering the best way to do this. TY.
