Macintosh overwrites handheld. Then click OK. See
"Customizing HotSync application settings" in Chapter 5 for
more information.
8. Connect the appropriate serial or USB adapter and the HotSync
cradle/cable to your Macintosh. See "Connecting the HotSync
cradle/cable" in Chapter 1 for details. To order an adapter, go to
the web site:

9. Connect your new handheld to the HotSync cradle/cable and
press the HotSync button. If the User pop-up appears, select your
user name.
Note: If you customized the modem setup on your old handheld,
you must re-enter the modem initialization string. See
"Connection preferences" in Chapter 6 for more
information.
Any passwords you set on your old handheld are not restored
during this HotSync operation. Records you previously
marked Private are still marked Private, but you need to
reenter a password on your new handheld.
Each handheld must have a unique name
After you complete the upgrade process described earlier in the
"Upgrade Information" section, your new Palm m100 series
handheld and your old handheld now have the same user name.
This is an undesirable situation. Each handheld must have a unique
name in order to prevent unexpected results during HotSync
operations, possible data loss, and other complications.
We strongly recommend that you perform a hard reset on your old
handheld. See "Performing a hard reset" in Appendix A for details.
A hard reset not only erases all data from the old handheld; it also
erases the name and makes that handheld a clean slate, ready to
receive a new name. The next time you perform a HotSync operation
with this old handheld, you are asked to give it a name. Be sure to give
it a unique name.
