Upgrading ASAs to a newer firmware help

[Gonzo1]

Hi,

I've not upgraded our ASAs in a while and need some help doing this.  We have 2 x ASA 5516s with Firepower and they are in an Active/Standby setup.

Here are some details:

1. I have a TFTP server, but am not sure which firmware to go to, I have done the ASDM, what do you suggest?
2. I think last time I did the standby ASA first last time and some how failed it over to so it became the primary then did the newly elected standby.

Any simple instructions would be great.

Thanks
