It had been used before, but is currently offline.&nbsp; I was following the upgrade path from 9.0.13 to 10.2.13-h4 (latest version I could find for the 10.2.* family).&nbsp; I was experimenting to see what worked during the upgrade process.&nbsp; I downloaded and installed 9.1.0 and then downloaded and installed 10.0.0 without installing the highest 9.1.* version before installing 10.0.0.&nbsp; Since then, the upgrades to 10.1 and 10.2 were successful.&nbsp; My question is: will there be a gap or any missing functionality due to me skipping the highest 9.1.* install?&nbsp; Thanks!</P> Mon, 03 Mar 2025 17:13:54 GMT https://live.paloaltonetworks.com/t5/general-topics/upgrade-path-question/m-p/1222452#M123472 T.Berthelson 2025-03-03T17:13:54Z https://live.paloaltonetworks.com/t5/general-topics/upgrade-path-question/m-p/1222453#M123473 <P>No you do not miss any functionality.</P> Mon, 03 Mar 2025 17:43:45 GMT https://live.paloaltonetworks.com/t5/general-topics/upgrade-path-question/m-p/1222453#M123473 Raido_Rattameister 2025-03-03T17:43:45Z
