Yeah, my thought was spinning up a 2nd appliance and importing the data into there if no other supported model was available.
One idea going forward might be to have LEM connect to the archive file via a network share and just reading it over that versus importing it at all. The idea is that these should only ever need to be accessed in special situations anyway and then detached shortly after so performance would not need to be the primary focus, just the ability to have it available. Thoughts?
