Is there a way to update Numbers 2.0 to 2.3? I have some documents that I prefer to work with in version 2.x because they look much better in that version, better contrast, colors etc. I've had both version 2.x and 6.x installed on my old Mac Pro. Now that I have a new Mac mini, I have installed 2.0 from the iWork .dmg. But since I have version 10.x installed as well, there seems to be no way I can upgrade 2.0 to 2.3. Any ideas?
