Can a storage node be shared by more than one server and will an older storage node release work with 7.x?

We have 2 storage nodes both running 6.1.1, with one library each, and they work with our older 6.1.1 server. However, we've just installed a newer 7.2.1 server on another box to replace this old server. However, until we do the permanent swap, it's using the same IP and host name during the day for testing, while the old server is down to avoid IP conflicts, and in the evening before the backups run, its IP and host name is changed back, and the nightly backups resume on the old server. This new host will use a third storage node and library that has not been set up yet, but would like to be able to also use and test out the other 2 storage nodes, but this seems problematic ...

Will it be necessary to re-run jbconfig on those storage nodes for their devices to show up on the new server even though the host name for the primary server is the same? Also, will the older 6.1.1 storage node server software work with 7.2.1? Would be nice; otherwise, we'd have to uninstall it and load 7.2.1, but then we could no longer use the storage nodes with our older 6.1.1 server, and that has to be available to run our backups until we do the swap. Guess we could down grade the software back to 6.1.1 and then go back and forth, but that's a lot of work to do every day.

Any advice would be appreciated.
