SSH identity changed on new Server - can't login over SSH!

Hi all,
I run a Ubuntu data server, with clients rsync'ing their data onto it via SSH. This was running 6.10, but i've upgraded to 7.10 today.

Everything has gone fine except that the SSH identity of the Server has changed. As my clients use password-less authentication using private keys, this is a bit of a pain as no-one can send any data (we use custom made software that doesn't give them the opportunity to accept the new host).

Is there any way to change the SSH identification back to what it was? I installed 7.10 on a new hard drive, so everything else from the working install of 6.10 remains intact. The IP address and hostname are the same too.

Any help would be greatly appreciated.

After some help on another forum, it was as simple as copying /etc/ssh/ssh_host_* from the old to the new system. Once that had been done, it worked fine.

Thanks for the reply :-)

Well as it's a critical server, and it's a relative new release, I thought i'd just do it on a new hard drive. Glad i did now

The rationale was that the original install of 6.10 had become messy. I'm not bothered about the LTS release, as this server will be replaced long before the support runs out.
