Subject: [ace] Please update nodeDB when upgrading systems


When upgrading a system and then pointing an alias (CNAME) at the old system, please remove the old system from nodeDB.  Leaving them both in there causes several problems.  If you don’t do this, it creates problems for things like the backup system and SSL certs.  For example , if you upgrade opsl00 with opsl77 and then leave a CNAME for opsl00 -> opsl77, remove opsl00 from nodeDB.



Thanks,

Anthony
