[Evolution] Data migration Evolution 2.24.5 to 3.4.3

[Brian A Anderson <BrianAAnderson q com>]

How do I migrate from one machine running Evolution 2.24.5 to another
machine running Evolution 3.4.3.

Please note that the older machine (running 2.24.5) is dying a slow
hardware death.

I tried backup on old machine and restore on new machine.
No go.  It appears that the data is totally different in organization.

Thanks in advance for any help.
