I attempted to migrate a vsphere 6.0 U3 environment to 6.7 U3. This included a VCenter (Win 2008), External PSC (Win 2008) and external MS SQL 2008 (Win 2008) to the VCSA with external PSC appliances.
During the PSC imigration the following error appeared – after the new appliance was deployed and old PSC turned off
Error: Analytics Service registration with Component Manager failed
In the log files (analytics_firstboot.py_6604_stderr.log) I could see the following error:
2020-04-21T19:11:27.717Z Failed to register Analytics Service with Component Manager: hostname 'jord-sso01.jord.local' doesn't match '192.168.65.8'
So the error appeared to be a reverse DNS entry on my NameServers – which I should have checked before upgrading. 🙂
