Up until recently, I was running Pagemaker 6 on my PowerPC Mac Mini (under OS9) but I have since changed to an Intel-powered Mac Mini.
Clearly, I can no longer run Pagemaker and need to upgrade to InDesign.
However, if I no longer have Pagemaker on my new Mac and then install the InDesign upgrade program (and it doesn't find a copy of Pagemaker on my Mac to upgrade from) how will I be able to install the new program successfully?
Will I instead have to buy a full copy of InDesign?
As long as you have the original PM CD and serial number, I think the ID upgrade installer will just ask for the PM CD to be inserted for a short while and / or the PM serial number to be typed into a dialogue box. This was the case when I upgraded from PM 6.5+ to PM 7 for Windows a few years ago. You don't need PM to be physically installed on your Mac. Hope this helps.
"The installation process for an upgrade requires that you enter the serial number from a qualifying product, on the same platform and for the same language version, as the upgrade product being installed."
