    We just got a new SSD at the office which we have installed in one of our MacPros, which believe it or not is still running Leopard. What we are wanting to do is install Lion onto this SSD (we've already purchased it on another machine and have made a bootable USB key) but weren't sure if there were any specific things we needed to do before we could do so.

    Is it as simple as running the installer and then it will ask which drive we want to install it on?

    We want to be able to dual boot (for now) between Leopard and Lion so we want to ensure we don't wipe the Leopard install drive.

    EVENTUALLY we WILL be wiping the leopard disc once we know everything has been backed up, that all our apps work in lion, and we've migrated all projects to the newest versions. At this point we want to make the SSD our boot drive. How do we go about doing that switch (ie taking a non-boot drive and making it such)

    Any help would be greatly appreciated!

    I assume Leopard is on another hard drive separate from the SSD. In which case, connect your Lion thumb drive, reboot and hold down option key and then select your Lion thumb drive as the volume to boot from. Then use the disk utility on the Lion thumb drive to format your SSD to GUID then simply install Lion on the the SSD (It will ask you to select a Target Volume).

    Once Lion is installed go to Sys Prefs>Startup Disk and select the SSD containing Lion and then click Restart. The computer should start booting from the Lion volume.
