I don't know if that's going to be available, and I don't believe it has any real value even if it were.
Honestly it will depend upon when you come to Liferay. If you came in under Liferay 4, 5, 6.0 or 6.1, you've likely done upgrades to get to newer versions or maybe you're still stuck where you came in because you follow "if it's not broke don't fix it" mantra.
If you came to Liferay since the end of 2013 you probably started immediately on 6.2 and have a "green field implementation".
Having gone through updates I can say that the green field environments are always easy to start, but upgrades are necessary to keep your data as you move forward. 6.0 folks, for example, won't throw away their environment to have a green field 6.2.
