So this morning was my fourth attempt to update one of the SonicWall units, I was migrating from a Pro 2040 (now EOL) to one of the shiny new NSA 2400 units, on paper it looked easy.

Update NSA 2400 to latest firmware, import config from Pro 2040, however this being the fourth attempt you can see how well it had gone in the past.

(Side note: The problem with upgrading the head office router is that people tend to get upset if there is no email for more than a couple of minutes!)

I’d try to do the swap over in the morning before the office opens in the past and been thwarted twice, and a weekend change out didn’t work so well either. This time however I’d taken the unit home over the weekend and set it all up….

- latest firmware, check
- imported config, check
- installed AD certs, check
- ensure all firewall rules in place, check

So looking like we’re ready to try again.

Plugin, power up and connect to the admin interface, register the device, fails the first time, try again and this time the registration is successful, sorted.

Now to start checking all the services to ensure everything is working as it was.

This time around there is no DHCP crash, no failure of the WAN traffic, all good.

So migration from Pro 2040 -> NSA 2400 – DONE.

Just got to migrate 9 Pro 1260′s now
