You have a couple ways to accomplish this. If you have all your data on your E2, you can install palm desktop on the 2nd PC and skip the initial sync. Once installed, you can then change the hotsync conduits to handheld overwrites desktop and then sync.
The other option is to export your data from the 1st PC then import on the 2nd PC. Here are the instructions for exporting.
The best way to preserve your data is to export the data in each component in Palm Desktop to a seperate folder on your PC.
Create a new folder on your PC somewhere that is convenient. Name it something like Palm Desktop Data. Click on the link below and follow the instructions on that page for the export procedure.

Make sure you select all for the range in the export window.
With the data saved in the folder you created, make a copy of that folder and save to a flash drive, cd-rw or external hard drive.
Anytime you make a change in Palm Desktop, export the data that was changed to that folder and save again to the external media.
With this process you can always import the data back into Palm Desktop anytime you have a problem with the data in Palm Desktop or if your computer/hard drive/device crashes.
