Best way to Unarchive the process

Hi All,

Imagine there is a main process model and some sub process models. Now the task is in one of the sub process and lets say its in 3rd PM. and the case got cancelled manually and all the process models are archived. Imagine I want the data back using un archiving the process.My questions would be

1. Can I get the process in active state from where it started.
2. Can I make the task from which it got cancelled to active.

Could someone suggest. TIA :)
