This is an original planning guide. It is not a vendor manual, an official standard, or legal advice. Example addresses use documentation ranges. Review every command before you paste it.
What this hour is for
FortiGate policy is zone to zone. The converter drafts one SRX policy. You write the zone map. Any-to-any is deleted. The SRX backup stays. Install is the apply. This page does not install a policy on a gateway.
One policy. Secrets are redacted. A VDOM, if you use one later, is a name in a later ticket. Do not select every gateway in the note.
Management is not published to the world.
The change you can finish
Apply nothing during the writing of the note. When the lab window opens, it is one change on the device named in the ticket. Read the draft, then the device, then decide.
Rollback is the file or the revision you saved first. You do not invent a rollback after the only copy is gone.
- Pick one policy.
- Convert.
- Write the zone map.
- Delete any-to-any.
- Keep the SRX backup.
- Do not install.
Mistakes that outlive the command
Juniper SRX to FortiGate Migration Guide goes wrong in a small set of ways. The list is here so the ticket can forbid them before the window.
- An install from the draft.
- Any-to-any kept.
- The backup discarded.
- A secret retained.
- Every gateway named as the target.
Decisions to write down
One decision for Juniper SRX to FortiGate Migration Guide: One policy is the scope. Zones are mapped. Any-to-any is gone. The backup exists. And nothing was installed.
Checks before you call it done
Confirm this before you call the change done: The policy is named. The zone map is written. The backup is named. No secret remains. And no gateway was installed. If one of those fails, stop.
Before you leave the device
Juniper SRX to FortiGate Migration Guide ends when the hostname on the device matches the hostname in the ticket. If it does not, you are on the wrong box. Stop. A command that succeeded on the wrong box is not progress.
The draft stays a draft until a person has read the names in it. A generator does not log into the device and does not know which interface is the uplink. You delete a line that names a device, a zone, or a prefix you did not write down.
0.0.0.0/0 is not kept because a sample included it. A source you can say is the source you keep. 192.0.2.0/24, 198.51.100.0/24, 203.0.113.0/24, and 2001:db8::/32 are documentation. They belong in the note. They are not prefixes you type onto a production device because they appeared in a draft.
prompt-for-this is a reminder that a secret is missing. It is not a password, a key, a community string, or a pre-shared key you save in the ticket or in git. The real secret stays in the store.
One change is the window. A VLAN and a routing protocol and a VPN do not share it. If two things move and the result is wrong, you will not know which one did it. The next feature waits for its own page.
If the same step fails twice, stop for the day. The failure is the result. Adding a forum command beside a half-applied config produces a device nobody can rebuild. Restore the copy you took first.
A second person reads the device name and the change aloud. If they cannot find them in the ticket, the note is not done. Silence is not agreement. Then leave the device alone.
This page is a planning guide. It is not a vendor manual, not an official standard, and not a permission to touch a network you do not administer. The pillar guide owns the wider design. This page owns one lab proof.
