Installing applications twice on the same computer for different OS

Hi. I currently have the latest version of Tiger installed on a G5 PowerMac. I'm planning to replace my boot drive w/ a larger drive and partition it, using one partition for Tiger and the 2nd partition for Leopard (10.5.8). As I understand it, applications must be installed on the same partition w/ the OS so I assume I will have to reinstall any applications that I am now using w/ Tiger onto the Leopard partition as well (if I would also like to be able to use them w/ Leopard). This will result in applications being installed twice on the same computer, one installation on the Tiger partition and a 2nd installation on the Leopard partition. Has anyone done this successfully w/ Adobe CS3 applications? I'm not sure if this question might be better suited for an Adobe forum but I was hoping someone here might be able to provide some helpful feedback. I would also like to know if there are any other issues that I should be aware of concerning installing the same application on two different partitions. Thanks for your consideration. (I would also like to be able to do this w/ FCP6.)

Hi Jack,

First finish 10.4 Install, then clone the 10.4.11 patition to the one you want to use for 10.5...

Get carbon copy cloner to make an exact copy of your old HD to the New one...

There will be no issues with two applications installed on two partitions.

However I cant understand why you want to do this, unless you have a very specialist application that cant run in Leopard.

CS3 installed on a single partition drive with Leopard will be a much more healthy system for CS3.

Thanks BDAqua. I do have CCC and already have my Tiger partition cloned so I'll just clone it again (maybe a more bare bones version) as you suggest and install Leopard on that partition.

Thanks for your reply Gary. I did have some concerns about certain apps maybe not running up to par in Leopard and wanted to make sure I could switch back to Tiger if needed. Also I have a few apps that require Classic support and I'd ideally like to have that option available to me.

You're saying that Leopard running on a 2nd partition will not be as stable as if it were the only OS installed on a non-partitioned drive?

Yes. Particularly if you want best performance with Photoshop. As you have a G5 Power Mac, add a second internal drive with the second OS installed to create a dual boot machine.

Well, I'd clone a full version of 10.4, then update that clone to 10.5, then 10.5.8, you should have the best of both OSes then... & all your Apps. 🙂

Oh, doesn't matter if it's on another partitition or another drive.

Okay. I do already have a 2nd internal drive installed that I use as a scratch drive but I could also make it my Tiger boot drive. Leave it unpartitioned also?

Oh yes, I would clone a full version of 10.4. By bare bones i meant that I when I use CCC to clone my original Tiger drive to another partition or drive for the Leopard upgrade, I might not clone some of my older apps and files, etc. Is that not a good idea?
