Editing my comment as I too finite in my reading of the question.
xavierpitz method mentioned below should do the trick. You'll just need to make sure the new igroup is configured for FCP

What about :
- Stopping IOs to the LUN.
- Offlining the LUN.
- Unmapping the LUN from the iSCSI igroup.
- Mapping it to the new FCP igroup.
- Re-onlining the LUN.
I mean as long as the content of the LUN : partition table / filesytem(s) included are compatible with the OS from the target FCP server, why not ?
This is how I already migrated LUNs from iSCSI to FCP servers, but if you want to backup/restore it's up to you.
You could at least try . Take a snapshot before doing so.
