Problem:

When publications go out of date, they are completely useless and all changes made to them can not be leveraged in any capacity.  In LXC the situation is even more dire as customers do not have control of when Liferay will be updated.  This can cause an extremely large amount of changes to become useless.

At the same time, the is a danger in allowing publications to be used as is after updates because the database schema may have changed between updates.

Desired Outcome:

Provide users with the ability to still leverage their out of date publications in some capacity after upgrades.
