The Version 5.1.3 GrampsPortable (PortableApps for 32bit Windows; OS version 7 or newer ) has the following initial warning about being unable to read data from 3.x version:
This sort of message scares new users expecting stability & data portability. (And the overlong paragraph of text makes the solution seem more complex than it is.)
Is the warning accurate? And, if so, can anything be done to make data migration less intrusive?
(I have lost data via the XML export/re-import process — even when opting to include all data, including private & living person data. At its broadest, using Export instead of backup prunes objects not connected to Persons. It seems like the recommendation should be Backup to XML, not export.)
