Older releases required less HW resources, but it is required to increase it now. You can see reference <A href="https://www.cisco.com/c/en/us/td/docs/security/firepower/quick_start/fmcv/fpmc-virtual/fpmc-virtual-vmware.html" target="_self">here</A>.</P> <P>From v6.6.x, oldest FTD you can manage is 6.2.3, as you can see in <A href="https://www.cisco.com/c/en/us/td/docs/security/firepower/660/relnotes/firepower-release-notes-660/compatibility.html#reference_A0CAB7C28A2B440F8F901D316D6684F4" target="_self">compatibility matrix</A>.</P> <P>If you want to do hitless upgrade, then you'll need to do upgrades of both FMC and FTD(s), one at a time, to specific intermediate releases, and as per compatibility matrix.</P> <P>Kind regards,</P> <P>Milos</P> Fri, 16 Dec 2022 07:23:17 GMT https://community.cisco.com/t5/network-security/old-version-of-ftd-is-good-when-it-is-added-to-the-new-version/m-p/4740265#M1096021 Milos_Jovanovic 2022-12-16T07:23:17Z
