I do not have Ipoker on my computer, but it may be possible to move the notes from one ipoker skin to another.
You have to find if they reside the notes on your computer or on their server. For example,
pokerstars puts the notes on your computer. You will notice if you log onto PS from another computer you do not have your own notes.
So just go into the directory where ipoker resides on your computer and look for a file titled 'notes' or something similar. If you have that file, you can transfer it to the other skins you will be playing.
A quick note to support asking if notes are in a file on your computer may be easier.
