Could please advice what's the upgrade path to upgrade FMG from 6.4.10 to 7.2.2 ?
Upgrade paths can always be found in the Upgrade Guide:
based on the paths outlined, you should be able to go to 7.0.5 and then to 7.2.2. Just be sure to upgrade any ADOMs if you are running 6.2 version Adom. 7.2 only support 6.4, 7.0. and 7.2 ADOMs.
According to the release notes:
You can upgrade FortiManager 7.0.1 or later to 7.2.2.
You can upgrade FortiManager 6.4.0 or later directly to 7.0.1.
Thank you for your answer,please,is there any issue or misbehaviour whene upgrading to 7.2.2 ?
Because i have a fortigate v6.4.11 it's not compatible with FMG v7.0.1,so could i upgrade the FMG v6.4.10 to 7.0.5 and then to 7.2.2 ??
upgrading to 7.0.1 should not be an issue as long as you are not trying to push any configurations while in that version. Just wait to make changes until you are on 7.2.2 FMG.
