Setting:

• User uses JabRef 2.11 to work with an external database
• User uses JabRef 3.6dev and connects to external database
• User sees no entries
• User switches back to JabRef 2.11.
• User sees no entries (to be confirmed)

Desired: The old entries should be shown in both cases.

Is that possible? Should the user use JabRef 2.11 to rescue his data?
