Cannot migrate interface - Integrate Interface greyed out

Running Fortigate on 7.4.5.

I have some VLAN interfaces that are part of a LAG. I need to move one of these VLANs out of the LAG and have it tagged on a separate physical interface (or perhaps a different LAG).

I did see the article https://community.fortinet.com/t5/FortiGate/Technical-Tip-Migrating-VLAN-interfaces-from-one-interface-to/ta-p/257285 suggesting looking at the "parent" where the Integrate Interface is available, but I don't have that. All the VLANs as well as the parent LAG have the Integrate Interface greyed out.

How can I move it? I really don't want to delete and recreate it as I have lots of policies linked I would need to delete and recreate too.

You need to remove all references to the interface in the config, delete it, and re-create accordingly.

Hello,

I believe that would be possible, but since the parent interface is up and in use, I am not sure it would be possible in that case.
I would suggest perhaps in a maintenance window to set the parent interface down, and after that try to move the subinterfaces.

In the end, I went with deleting it. It's a real pain as I have to now redefine all the policies...

@ezhupa, unfortunately, that's not really an option as the parent interface holds the entire network! Of course, had I known the limitation, I wouldn't have done it this way. I'm learning the delish little details of FortiOS :)

You are right, I can feel you.
