Edit: Sorry, should say Firepower Management Center.
So at that top of the download page it says "If you have not already upgraded to the 6.2.3 release, please use the 6.2.3-84 upgrade package for Firepower Management Centers". It also says do not use 6.2.3-83 due to bug CSCvi7752, "upgrade to 6.2.3 fails with post install database integrity check error".
I'm running FMC on VMWare for which only 6.2.3-83 is listed as available for download. Is anyone running this version? Do I need to avoid it?
Separately but somewhat related, the release notes say:
"New features in Version 6.2.3 involve sharing data with Cisco. Web analytics tracking sends non-personally-identifiable usage data to Cisco, including but not limited to pages viewed, the time spent on a page, browser versions, product versions, user location, and management IP addresses or hostnames of your Firepower Management Centers.
You cannot opt out of web analytics participation during the upgrade process. You can either disable web analytics after the upgrade or not install the upgrade".
That seems kind of wacky to me. I expect that kind of thing with a phone app, not commercial-grade software that costs lots of money.
