Hello,
It has been many years since I've used a Palm OS device, however, when I did, I used
Blue Nomad's
BackupBuddy software to migrate from device to device (PalmPilot Professional -> Palm III (IIIe) -> Palm Vx) before moving to a Windows CE-based device (Compaq iPaq).
From what I recall, your plan
should work, however, you might want to consider verifying that with the experts in the
Palm Forums.
You might also want to consider purchasing a program like BackupBuddy, anyways: I originally switched to it not because of upgrading, but because of problems syncing data between my PDA and my PC. I suspect that Palm's HotSync software is more reliable and less crash-prone these days, but it might not be a bad idea to get a copy just in case. A copy for personal use is fairly inexpensive.
Regards,
Aryeh Goretsky
