I had included this change of using the same NB UUIDs in SB for Datapath-bindings here [1] as part of this series - [2]. Please see the comments in [1]. Later Lorenzo took over this patch series and dropped the patch [1] from it. [1] - https://patchwork.ozlabs.org/project/ovn/patch/20250110162652.3550775-1-num...@ovn.org/ [2] - https://patchwork.ozlabs.org/project/ovn/list/?series=439760&state=* The main concern is that both LS and LR can have the same uuid. IMO this can happen only if LS and LR were created by passing "--id=<SAME_UUID>". I personally think we can overlook this corner case and document it and suggest the users to recreate such logical switches/routers before upgrading.
