You should be able to do this fairly easily. Power the primary down and the standby should be active. Make sure your new pix has the same code of PIXOS and the same ASDM/PDM if you are using it and then configure the new pix as you would a secondary pix, see this link -

then power up the new firewall. It should sync it's config from the standby and then if needed you can force the failover back to the new firewall as primary.

That does sound like what I thought would be the best way to do it. I have copies of the IOS and ADSM to copy to the new unit. Thaks for your help
