Hi- I will be upgrading the ISP for my site and I was wondering what the best way to do that would be, especially in regards to our email server. I've done some research and it appears that I can connect two live ISP connections to my Cisco ASA 5510, but that I can only have one ISP connection live at any one time --so basically one is active and the other is the failover. So basically, I have:
ISP A - Old ISP, which will be retired in 8 months
ISP A Public IP
ISP B - New ISP
ISP B Public IP
I have the live Cisco ASA 5510 and a spare Cisco ASA 5505.
What's the best process for this?
