Upgrade to 10.5 help!

[gigapocket1]

Okay. So i have a Powermac G5 running os x 10.4.. I also have the macbook pro and a macbook air.. I have the os x 10.5 installation for both of them. Is their anyway that I can use those installation disks to upgrade to os x 10.5?

Don't think so. The discs are machine-specific. You'd need a retail copy.
