Kevin,

The problem with our situation is that it's all inside Docker so I don't
think I can just stop the registry and proceed. That's why I was asking if
it sounded feasible to just say "hands off for 5 minutes while we copy the
data."

Also, what is the maturity level of the GitFlow option at this point? That
was particularly attractive as a storage solution because it should make it
much easier to export everything from our dev team to our end users.

Thanks,

Mike
