Changing Wan IP addrss Sonicwall pro 3060

We are changing ISP's and will have to change the Sonicwall Pro 3060 WAN address. By doing so are there any gremlins that will show up as we have several forwarding rules setup. Most critical i don't want the eMail server affected after we change WAN addrreses.

Thanks

Speaking to the email part in particular,

Make sure your mail server has a matching A and PTR record in DNS for whichever IP(s) it will be sending from.  I'm assuming you already have an A record for your current server, so you will probably only need to update the PTR of your new IP to point to it.

Remove the old IP from your SPF record and put the new IP(s) in.

If the hostname of your incoming server is the same, then you do not need to modify the MX records.

When you change the WAN IP, it should update the associated address object. As long as your firewall rules and NAT policies are using the default address object and not one you've created, then all the policies and rules will automatically update when you change the public IP address.

Not a problem I understand that part.  I was concerned that when I changed the WAN IP address on the Sonicwall and put it on the new ISP's  network that the firewall would not work properly. I did not know if the new WAN address would require other configuration changes on the  firewall

Apart from suggestions that papertrip made, just make sure you get the public IP, subnet mask, gateway, DNS1, and DNS2 from your new ISP. I'm assuming that it's a simple implementation of the sonicwall without things like HA, WAN failover, etc. Is that the case?
