I have a really old SRX100H2 firewall. I would like to migrate to SRX300.
Is the migration as easy as exporting and importing the config?
Some migration tips would help greatly.
Thank you very much.
Unfortunately you cannot copy the configuration there are a number of differences.
1-SRX100 is fe interfaces and the SRX300 series are ge interface
2-there is a major change in how layer 2 configurations work. Junos has merged the MX version of layer 2 into the SRX chain. The new system is called ELS (enhanced layer 2 services). Here is the documentation on getting started with the changes.
Thanks for the guide. To simplify it further, do I use the ELS translator tool to translate my old configuration, from there, manually checked if the translated configuration is correct?
Yes that would work. I didn't mention the ELS translator because I was not able to reach it and wasn't sure if that was just a permission change or if the tool was no longer public.
Also note the interface name changes across all services in the configuration as well.
