How to combine android data with apple

Hi all,

For the past two years I have been using an Android phone as private and iPhone as professional. Now I would like to move all my data (mainly contacts and photos, I can deal with apps manually) to iPhone. What is the best way to do it without losing any data? As I can see, "Move from Android to iPhone, iPad or iPod touch" Apple support manual relates to new iPhone and I am not sure if it's gonna work to "combine" data from two phones.

Best,

Kacper
