I need to know that too.

This article is pretty easy to follow and contains the steps needed to transfer your iPad content to the new computer.

This thread also discusses how to move the iPad content to another computer.

You followed these steps and it did not work for you? This is copied from the discussion thread. When you get to step 5, try restoring from the backup that you just created in step 4.

1) Without connecting your iPad to your laptop, start iTunes. Click on Edit. Click on Preferences. Click on Devices. Check the box next to "Prevent your iPod etc. from automatically syncing." Click OK.

2) Now connect your iPad to your laptop and start iTunes.

3) When iTunes starts, right click on your iPad under Devices in the left column. Select Transfer purchases etc.

4) After it finishes transferring all your apps to your new laptop, right click on your iPad and select Backup your iPad.

5) After it finishes backing up your iPad, right click on your iPad and select Restore etc.

6) After it finishes restoring, left click on your iPad , then click on the Apps tab on top, and check the box next to Sync Apps, then click on Apply below.

If everything on your iPad looks good after the sync, go back and click on Edit / Preferences / Devices and UN-check the box next to Prevent your iPod etc. The only other thing you may want to check is if your contacts, bookmarks, etc. are syncing correctly now. If not, go to the Info tab after connecting and make sure you indicate which features you want to sync with what sources.

From here down are my remarks and not the OP's remarks from the other discussion ....

Any music content, photos or movies in your iTunes library that was not purchased in iTunes will have to be transferred from your old computer to your new one. If you don't have a backup of the old iTunes library to access, you have to start all over again by importing your music, photos and movies into the new iTunes library in order to sync the content to the iPad.
