What to check before upgrading the forest functional level

Our system have active directory server 2012 r2 and forest functional level 2008 R2 and domain function 2008 R2 . Child domain functional level 2008 R2. Now we want upgrade functional level to 2012 r2 and after that to domain functional level . Please guide help me what to check before upgrade ? And can downgrade it have problem ?
  • I'd check that the domain health is 100% before making any changes or upgrades. (dcdiag, repadmin tool)
