During our recent upgrade to SDL Tridion Docs 14 SP2, we were in a transitional period, where we were briefly running both Tridion Docs 13 and 14 simultaneously. It would have been helpful to be able to access both our older Oxygen installation pointing to Tridion Docs 13, in addition to our newer Oxygen pointing to Tridion Docs 14. This can be done with Publication Manager, so I don't see any reason why the Authoring Bridge can't be updated to match a similar functionality.
