    I've always had bad luck when upgrading from one OS to a newer one. So, I have followed advice from a number of people, and created a partition where I have installed Yosemite to test it before abandoning my old Mountain Lion. However, now I don't have access to my apps, so how can I test Yosemite? Is there a way to access to the apps on my HD drive from the new partition? I've considered using Migration Assistant, but that seems to want to move things from the old partition to the new one. I don't want to move anything, in case I decide I want to keep on using Mountain Lion.

    You can access the other partition from the new OS. Just open disk utility and make the partition mount. be sur to use an Admin user account.
    Then select the Applications folder of your old user and be sure you have the privileges, in the finder get info and provide Read & Write privileges.
    Certain Apps will need to be updated in order to work in the new OS.
    Another approach is to log in in the App Store with your account and install only those that are relevant for your test.

    The migration assistant is goos to know exactly which Apps will not work and to move all your date to the new partition.

    What I always do when installing a new OS is use another Hard Drive/SSD do a clean install and then use migration assistant.

    Remember to make some good backups.
