How to update ini file in advance of SSH host key changing

We use automation and simple 'DOS scripting' - sites and ini files.
3rd party that we connect to has told us they will be changing their SSH keys in a couple of weeks, and have passed us the new public certs.
Question is how can I (or is it even possible to) update the ini file in advance of the change so that we dont get prompted to accept the new host key when they do finally switch over?
Thanks
Darren.

Re: How to update ini file in advance of SSH host key changing

If you use scripting, you should have your host key fingerprint in your script in the -hostkey switch.

You can put fingerprints of both the current and the future host key to the switch, semicolon-separated:
open sftp://username:password@example.com/ -hostkey="current fingerprint;future fingeprint"
