Update from 5.4 to 6.0

hi

you do not need to format the box. the recommended way on the support side usually works without problems. I

already mentioned that you should create a backup before :)

regards

If you want to keep (and upgrade) the current configuration you must use the upgrade path AND check at each step if there is any upgrade error (diag debug config-error-log read). From experience it's particularly tricky from 5.2 to 5.6 if you are using wildcard FQDN (that wasn't a different object type in 5.2, introduced in 5.4 and enforced in 5.6 if I remember right). If you were using those and didn't change the type / fixed the config-error-log it's going to snowball, those object won't be created, any group using those object won't be created, any policy using non created objects or group won't be migrated either. So you might end with a massive and very unpleasant to fix error list.

If you want like you original post seems to suggest starting from scratch you might want to factory reset you box then apply the 6.0.4 firmware by tftp (or from GUI) and redo a factory-reset after just to be sure.

Hi

Is there a reason to go to 6.0.4 ? a bug you need to fix ? Otherwise i would recomend to upgrade to latest 5.4.x

FGT1500D is fine in 5.4. (nor 5.6.x nor 6.0.x still imature).

You do noot need to erase the box.

You take configuration backup after every upgrade, you upload backup, Primary sends the upgrade to Standby (if clustered) and then the Primary is upgraded. Upgrade in Fortinet is smooth (have done many in lot of different boxes)
