What about upgrading a software probe?

I just do a "git pull", make a new .deb and "dpkg -i
atlasswprobe-5010-2.deb", but something went wrong.

My probe is now disconnected (

*systemctl status atlas*

I think that "dpkg -i ..." generates a *new ssh key pair*:

ls -l /var/atlas-probe/etc/
total 8
-rw------- 1 atlas nogroup 1811 *Mar  2 12:36* probe_key
-rw-r--r-- 1 atlas nogroup  387 *Mar  2 12:36* probe_key.pub

Questions:

1) It's possible to upload the new pub key without re-register my probe?
2) it's possibile to preserve the keys during upgrade (mark as conf  file
in .deb? ) or I need to make a backup before upgrading?
