I strongly recommend to read the release note to find any restrictions that are special for your kind of deployment. In general you need a min. v8.01.01.0251 to upgrade to the latest v8 and a min. of 07.31.06.0007 to upgrade to v8.01.01.0251. So you'd need at least two upgrade steps.
AP4102 is listed as supported so you shouldn't have any problems.
