Will Upgrading from SunSSH on Solaris to OpenSSH break existing trusts?

I'm having one hell of a time establishing trust relationships between accounts existing on Solaris and RedHat.

Solaris are primarily using SunSSH which I can/want to upgrade to OpenSSH however will doing this break existing trust relationships or will they still be intact?

I know the easiest way to determine this is to just try it on a non production host, however I was curious if anyone already had any knowledge of this?

The answer is no, but it will invalidate your known hosts file since the RSA/DSA fingerprint changes. Good to know and easy enough to work around.
