Migrate CS6 apps on new computers no original install disks

We Have 3 Mac Work stations. One running Adobe Cloud CC2014, two running CS6 apps that have been upgraded over the years from original CS3 install disks.

We purchased new iMacs running OSX 10.10 Yosemite. We want to run the already paid for and Licensed apps on new macs but a former employee ran off with the original install disks and all we have are the CS6 Upgrade disks.

We want to migrate our 2 sets of CS6 apps to new computer but as mentioned do not have the originals to build from, and run our CC2014 individual user account on our stand alone Mac set up.

How can i do this without having to upgrade to a Team members account. Our currant individual account does not expire till Nov 2016.

Thanks in Advance

Steve
