A host can have multiple exports from the same vv.
Why not just create a host set, add the hosts and export the volume set to it.
Then wait until you are sure it sees the new export and remove the direct exports leaving only the group export.
This should not delete the VLUNs, you should see the exports as "host in set" and any future exports will be done via the host set.
I would try it with some test VVs first, but I don't see why this shouldn't be an online process.

This is what I would do too, as in theory, as long as e host set is right, then the final removal of the single vluns should leave the working host set so the host should not notice any change.
